Unity 5.6 Not implemented: Class::FromIl2CppType and others

@Marco-Trivellato @jonas-echterhoff

Without any code change I simply upgrade it from 5.5 to 5.6 and this happens. Particularly when loading multiple files it seems:

Not implemented: Class::FromIl2CppType

UnityLoader.js:1 exception thrown: RangeError: Maximum call stack size exceeded,RangeError: Maximum call stack size exceeded

AND MULTIPLE ERRORS OF:

Edit: I have published a development build and I have more info but I don't understand anything. In that method only assigns a value to a Dictionary.

@JoshPeterson I am also getting this same issue. Didn't change any code, just updated from 5.5 to 5.6 and now the webgl build seems to crash when using dictionary methods. In my case, dictionary.ContainsKey:

With development mode disabled and enable explicitly thrown exceptions, I get the errors

Code (JavaScript):

1.  
2. Not implemented: Class::FromIl2CppType
3. exception thrown: InternalError: too much recursion
4.  

With development mode enabled and enable explicitly thrown exceptions, I get the error

Code (JavaScript):

1.  

 

Hello. I got this bug too in my game. There is stacktrace https://pastebin.com/3w5aNBDN and there is code which called dictionary implementation: https://pastebin.com/Ntbriupc (line 15, and key wasn't NULL). Please help with solve this crash. It is not 100% repeatable, but I don't like that game will crash some times when it will call this code.

 

Hi there,
I got an error that looks like the previous one, with WEBGL in unity 2017.1.0f3.

Any suggestion?

 

ok. done.

 

Hi more on this:

I have found that when doing:
Hash128 manifestHash = assetInfo.BundleManifest.GetAssetBundleHash(assetInfo.BundleName);
request = WWW.LoadFromCacheOrDownload(assetInfo.FullBundlePath, manifestHash);

then in
string status = null;
request.responseHeaders.TryGetValue ("STATUS", out status);

i get the error inside request.responseHeaders.

So my guess is that the problem is when you get a stored asset bundle from the cache, it doesn't have the response headers, so it doesn't behave like an "abstraction of a response" hiding if you get form cache or internet.

For my use case in webgl, to download everything from internet again and again is a no go.

Do you have a workaround to this? anyone having the same problem?

 

oh, just to have all the information, the bug in issue tracker number id 938618

 

Sorry was the first time i was publishing a bug report and accidentally i unchecked the option to send the project . should i send another bug report? or how can i update this one.

updated the issue link to number only in the forum reply

 

One more question about project upload. It upload the code? i work for a company, i don't think they want to disclose the code.

 

Ok, i think the problem here in this post: https://forum.unity3d.com/threads/data-caching-on-unity-5-6-is-not-working.468305

is the same i am having, that happens in the cache of the asset bundle.

 

Has there been an update on this? I am also seeing these issues on 2017.1.0f3 as well as a "GetInterfaceInvokeDataFromVTable" exception.

 

Has there been any progress on this? We are also experiencing this issue.

 

So I solved the issue, probably not the same issue reported here. We were getting the same error (Not implemented: Class::FromIl2CppType) but it was caused by a null reference. The error was misleading imo but pretty sure that's down to a WebGL thing and not Unity.

Thanks.

 

We're having the same issue on our project. Not able to narrow it down with logs. Posted a bug report 969211

 

I know this is quite an old thread - but I was wondering if there was a solution for it? I've been trying to build my project in 2017.4.16 but I'm getting this error, which in turn causes a "Uncaught RangeError: Maximum call stack size exceeded" error after generating around 5000 of these errors.

I've had the game running on Unity 2017.4.8 successfully, but have since updated to the latest and also moved over to .Net 4.6 is that makes a difference? I haven't tried to build it with 3.5, as it would require a few changes.

The game is also being launch through Facebook using their current SDK (7.14)

 

Will do

 

Hi JoshPeterson

Did you find the issue of this problem (Not implemented: Class::FromIl2CppType)? We are kind of stuck with this issue in Unity 5.3.8f2 (Yes pretty old, we know... but can't upgrade yet). Is there something we can do to avoid this? Is there any more clearance about this issue? I hope you can shed some light on this.

Thanks in advance.
