NotImplementedException Using 2019.1a11

I get an error that I don't know of what it means. Using 2019.1a11.
Do I need to file a bug report for this?

 

What were you doing when it popped up?

 

Openend unity, I can clear the errors in the console and after they come back when I press play

 

We encounter the same error (written twice in the console) in our project (Unity 2018.3.1f) every time Unity compiles code or enters play mode

Code (CSharp):

1. NotImplementedException: The method or operation is not implemented.
2. System.Environment.FailFast (System.String message) (at <ac823e2bb42b41bda67924a45a0173c3>:0)

10. UnityEngine.UnhandledExceptionHandler:<RegisterUECatcher>m__0(Object, UnhandledExceptionEventArgs)

there are strange symbols in the log, they were replaced by *** in the log I've posted because this forum struggles to display them and the following text becomes reversed (in most of the apps)

 

Did you upgrade a project from an earlier unity vension ?

It seems that is where it happens for me, and since this project is so large I can't send a bug report for it ( more than 10 gb )

 

Yes, our project was updated from 2017.4.6 Unity version. The exception is not reproduced in new projects

 

Case 1118695

It seemed to have something to do with an .dll of an asset store package in my project, and since the error came after upgrading it is most likely because of an api change in unity.

Would it not be possible for unity to show what dll is generating the error?

I got this answer from Unity QA:

 

I keep getting similar errors, After changing the script Runtime Version from (.NET 3.5) to (.NET 4x Equivalent) It start showing this error in the editor and in play mode

Do you have any .dll's ?

 

Yeah, It was a .dll after all! For me, I was using a plugging call "Only Renderer". If you want me to provide you with more details about the .dll file send me a message. Good luck!

Got the same error for a project which contains an obfuscated dll with Unity 2018.3.0f1:

Code (csharp):

1. NotImplementedException: The method or operation is not implemented.

Yes its very cryptic, and any newcomers to unity will pull their hairs out why this is happening, I hope unity will implement a way to see the source file that generated the error.

 

I was thinking about if I should do a feedback item, but since feedback is now dead
( https://forum.unity.com/threads/the-future-of-unity-feedback.633241/ )
I will just trust that this issue is now known, and that if anyone encounters this error they should report it in this forum.

 

https://github.com/Unity-Technologi...5/mcs/class/corlib/System/Environment.cs#L921

Found that

System.Environment.FailFast

is not implemented in mono.

Code (CSharp):

1. [SecurityPermission (SecurityAction.LinkDemand, UnmanagedCode=true)]
2. public static void FailFast (string message)
3. {
4.     throw new NotImplementedException ();
5. }

And it should be implemented as an internal call like in CoreCLR:

https://github.com/dotnet/coreclr/b...CoreLib/src/System/Environment.CoreCLR.cs#L36

Code (CSharp):

1. // Note: The CLR's Watson bucketization code looks at the caller of the FCALL method
2. // to assign blame for crashes.  Don't mess with this, such as by making it call
3. // another managed helper method, unless you consult with some CLR Watson experts.
4. [MethodImpl(MethodImplOptions.InternalCall)]
5. public static extern void FailFast(string message);

same error howt o resovle?

 

hi can u please help us with this how to resolve the issue

 

Try to remove every single .dll file from your project and reintegrate them one by one until you found the one causing the issue. Knowing exactly what the issue in the file its time consuming and you will need external tools/software to inspect the files.
