Code Gen related InvalidOperationException with latest Packages

Today I updated all the packages I'm using and now I'm getting a series of errors claiming to be code gen related, I'm getting these from my systems but also from Unity written systems like ExportPhysicsWorld and CopySkinnedEntityDataToRenderEntity, HybridRendererSystem etc. Anyone have any idea what these mean? Is there something I haven't enabled?

I'm on Unity 2020.1.0b9
Burst 1.3.0
Collections 0.9.0-preview.5
Entities 0.11.0-preview.7
HybridRenderer 0.5.1-preview.18
Jobs 0.2.10-preview.11
Unity Physics 0.3.2-preview

 

I haven't seen any warnings around Entities.ForEach component types, I am using a few [GenerateAuthoringComponent] attribute components to set prefabs to use in ECS, I thought for a second I might have seen some warning related to those, but I can't seem to make that show up again.

 

Same core issue different path to it. 2020.1 B10 latest entities.

Please share Editor.log when this happens. It will help tell us whether this is an issue with the IL post processors not running or if it is an issue with the individual IL post processors themselves.

 

Today I tried this again (I had backed out the changes because I couldn't continue with nothing working). I can't explain it but now with the entities package updated to 0.11.0-preview.7 it's working without the code gen errors. I had done this twice before and gotten the error so I can't explain what changed...guess I'll call it good luck.

 

unity version? I still got this error in build(

 

I'm on Unity 2020.1.0b10, it's odd because when I first updated to b10 I tried it and it failed with the same code gen errors, but for some reason it's working now.

 

@lukaszunity Update uity to 2020.1.0b11 and still got same exception after build

same error if built with il2cpp or mono with last entities package. No error after downgrade to previous

 

It looks like the Editor.log you shared does not contain the error message in your post. Did you perhaps share the wrong file?

 

So after a few weeks of stabilizing some major features in my game, I started attempting to make builds again. And regardless of what kind of build I try to make (dev or release), I am running into this same issue. I am reproducing this 100% of the time. At first I thought this was a known issue that is being worked on from this thread: https://forum.unity.com/threads/entities-0-11-build-crash.903413/

I am still on 2019.3.12 and unfortunately I cannot downgrade to a previous version of Entities because breaking changes made to ComponentSystemGroup make it impossible for my project to be compatible with both Entities 0.10.0 and Entities 0.11.0.

If there is a sequence of steps that I can perform, such as closing the editor, deleting specific temporary files from the project, opening the editor and project, doing some specific things like enter and exit play mode or set up a new build configuration, and then build, I can do that and send whatever files necessary.

 

Error not in build process, in application on mobile phone then it launched

 

I'm getting the same issue on 2019.4.0f1 LTS.
Burst 1.3.1
Entities 0.11.0

The game runs fine in the Editor but falls over when I run the build.
Specifically on these lines:

Code (CSharp):

1. blobAssetStore = new BlobAssetStore();
2. GameObjectConversionSettings settings = GameObjectConversionSettings.FromWorld(World.DefaultGameObjectInjectionWorld, blobAssetStore);
3. ballEntityPrefab = GameObjectConversionUtility.ConvertGameObjectHierarchy(ballPrefab, settings);

I'm trying to build your Unity DOTS Pong tutorial.

 

I just experienced this last night with 2020.2a13.1691, Entities 0.11.0p7 and Burst 1.3.1, when entering play mode. Code was successfully compiled but errored at the start of play. Occurred when editing classes related to SystemBase & ForEach.
Restarting the editor several times had no effect, but was resolved by deleting my library. Cant seem to replicate it though.

 

I deleted my Library and built the game again.
Unfortunately I'm still experiencing the issue.

Edit 1:
I logged a bug report with all my project details on Case 1255997

Edit 2:

Ok so I got it working now.

Originally I had everything in the Awake() method, as per the Unity DOTS Pong tutorial.
Out of interest I changed the Awake() to Start() and now it's working!

Seems like it's a timing issue might be that the EntityManager doesn't exist yet when the Awake() is running.

It's my best guess

 

I just started getting:

InvalidOperationException: This should have been initialized by code gen

in all sorts of random DOTs code after updating a microsplat package.

I deleted the Library folder and it resolved it... lost an hour for this though... Unity feels so fragile to use these days.

2020.1b5 with latest dots packages.

 

@jdtec I hear you, but just keep in mind that the forefront of technology will always have breaking changes and bugs.
Which is why they have their LTS releases once a year with solid and stable features.

I had to make the call now to stay on 2019 (LTS) if I actually want to complete my game.

But I don't stop playing around with 2020+ features and doing a few POCs here and there.

 

Trying to render using entities and everything works fine in the editor.

But in the exe nothing renders and the log shows two

InvalidOperationException: This should have been initialized by code gen

and a million

InvalidOperationException: Reflection data was not set up by code generation

.

I'm using "Unity 2019.4.2f1 (64-bit)". First I installed the package "Unity Physics" (v0.4.0) and then "Hybrid Renderer" (v0.5.2).

I've tried deleting the Library folder.
I've tried making a prefab with the "ConvertToEntity" script in the Resources folder.
I've tried calling

Unity.Entities.DefaultWorldInitialization.Initialize("TheWorld", false);

.

None of that works. What am I supposed to do?

I'm doing everything from C#, building all entities manually from scratch. Everything works in the editor so I figure it is some initialization problem or that something important gets stripped from the build.

Here are examples of the error messages (the log file keeps growing every frame with "Reflection data was not set up by code generation", all looks the same):

When I built the exe I got three warnings, the first said:

Library\PackageCache\com.unity.entities@0.11.1-preview.4\Unity.Entities\ApiCompatibilityLevelTest.cs(2,10): warning CS1030: #warning: 'Project is expected to have API Compatibility Level set to .NET Standard 2.0'

So I changed from ".NET 4.x" to ".NET Standard 2.0". Then I closed the editor, deleted "Library" and also "Temp" for good measure. Restarted the editor, auto-reimported everything, built the exe. Got two warnings instead of three, they were the same as before I changed from ".NET 4.x":

Code (CSharp):

1. Unable to find player assembly: C:\MyProjectPath\Temp\StagingArea\Data\Managed\UnityEngine.TestRunner.dll
2. UnityEngine.Debug:LogWarning(Object)
3. Unity.Burst.Editor.BurstAotCompiler:OnPostBuildPlayerScriptDLLsImpl(BuildReport) (at Library/PackageCache/com.unity.burst@1.3.0/Editor/BurstAotCompiler.cs:285)

11. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Then:

Build completed with a result of 'Succeeded' in 721 seconds (721332 ms)

And just like earlier, same errors and nothing gets rendered.

InvalidOperationException: This should have been initialized by code gen

InvalidOperationException: Reflection data was not set up by code generation

 

I got it working in Unity 2020.1.0b14 (64-bit) by making a new blank project and lifting over the old one piece by piece.

1. Made it using the "Universal Render Pipeline" template.
2. Deleted the sample stuff by Unity (I'd like to have a blank URP template without that demonstration scene, please).
3. Exited the editor, deleted the Library folder, started the editor again.
4. Enabled Preview Packages in Project Settings (the option has been moved there rather than having it in the Package Manager, which I find to be a strange move).
5. Installed Unity Physics (0.4.0-preview.5).
6. Installed Hybrid Renderer (0.5.2-preview.4).
7. Changed from ".NET 4.x" API compatibility level to ".NET Standard 2.0". (Left scripting backend as Mono for now.)
8. Copied the Assets folder from my old project.
9. Manually re-applied settings/layers/tags (no file copying here).
10. Made it possible to play in the editor (went from 15 sec between pressing play and actually playing to only 10 sec, nice).
11. Built the x86_64 exe, felt like it took less time than usual. For some reason the "Build completed with a result of 'Succeeded'" message in the console no longer says how many seconds the build took to complete.
12. It worked!

Still getting the warnings about not being able to find "UnityEngine.TestRunner.dll" or "Unity.PerformanceTesting.dll".

 

This still occurs (Unity & package versions listed below) and the temporary fix of deleting the Library folder is a huge thorn for development, especially in multiplatform games. It also doesn't solve the actual error -- the game runs in Standalone Mono builds without showing errors in any in-game UI, but the player log file still shows the errors occurring.

Due to specific platform requirements (eg. Nintendo Switch) I can't just upgrade the Unity editor blindly, and also can't upgrade my packages blindly due to other specific package requirements (eg. DOTSNET).

Version & package info:
Unity 2019.4.3f1
Entities 0.11.0-preview.7
Burst 1.3.0
Unity Physics 0.3.2-preview
Hybrid Renderer 0.5.1-preview.18

Also potentially worth noting: the DOTSNET package is the only thing in the DOTS stack active as soon as the game boots, and these issues appear after it finishes creating the server & client worlds. I have no DOTS coding of my own in the project at all.
Everything works fine on Nintendo Switch builds, but I get these issues on Standalone Mono & Standalone IL2CPP builds. Mono builds show the errors in some generated in-game UI but allow the game to continue running. IL2CPP builds freeze as soon as the first scene loads.

I'll try upgrading throughout the week -- packages first, and then upgrading the editor if that fails. This is preventing crossplatform testing though -- everything works fine on the Switch but I do need to test on other platforms.

If the only fix comes from upgrades that's going to potentially be painful -- the versions listed above are in a nice "sweet spot" of being exactly what all platforms & packages I need are requiring right now. Upgrading messes that up.

 

I have upgraded every package to the latest version & upgraded Unity to 2010.1b14 and it still does not work in Windows Standalone players. il2cpp players still freeze as soon as my first scene loads, and mono players still have the error messages pop up in the in-game error viewer. The errors are just like the ones from the original poster here. One error call example is shown below:

Spoiler: One of the error messages as in the mono player log file

This is the most-upgraded I can be with a Nintendo Switch multiplatform project right now. The Switch build still works perfectly fine and doesn't even get any silent errors like the Windows Mono player does.

Deleting the Library folder worked once or twice out of the ~6 or so times I've done it before a build. It's both not a consistent solution and also a time-wasting solution for multiplatform projects.

I have also just tried making a fresh project -- required DOTS packages & DOTSNET & nothing else -- and the fresh project with just the packages listed above (+DOTSNET) works fine. I'm not sure what could've changed in my original project to make it start breaking out of the blue though. Various other DOTSNET users do not get this issue so I would not like to blame that package, and the issue hasn't popped up in Nintendo developer forums.

I'm going to try & move over my original project into a fresh one, piece by piece, to see if that works. If it doesn't, I'll start thinking that it's something in my Assets

 

i am on unity 2019.4 for me, I got this error whenever I build addressable asset while in IOS configuration, and running the game in editor, if I clear the addressable asset and cause a code change and recompile the error seems to go away until the next time I build addressable asset again.

 

Having this occur on Entities 0.11 on Unity 2019.4.3f1
Just upgraded entities from 0.10 where this wasn't a problem.

Apparently, this is fixed in Entities 0.13 officially as of last weekish according to Unity support. But that requires Unity 2020. Womp womp.

 

According to the patch notes (https://docs.unity3d.com/Packages/com.unity.entities@0.11/changelog/CHANGELOG.html) it should also be fixed in 0.11, but for us in 2019.4.6 it is also not working. But with 2020 and 0.13 it is indeed working. A fix for 0.11 would be highly appreciated.

 

Any news on a fix for 2019.4 ?

 

+1 happens on Unity 2019.4.4f1
It seems like it happens after project switching.

Setting Burst to synchronous compilation + reimporting code only fixes the problem, but only temporarily.

 

Also, it seems to be happening more often when Auto Refresh is disabled in Preferences.
