L2CPP error for type 'System.Collections.Generic.SynchronizedCollection

[bwyyoung]

I got an il2cpp error below when compiling for iOS under Unity 2018.3.3f1: il2cpp.exe didn't catch exception: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

After I removed the CymanticLabs folder under assets, the project managed to build and run on iOS devices. It seems to be an issue with System.Collections being used in AMQP.

Can someone help?

Hi @bwyyoung, did you manage to solve the issue? Or did you find a workaround?

Thanks.

Same issue

[bwyyoung]

No I have not resolved this issue.

I recompiled the dotnet 4 version of RabbitMQ dll and Cymatic labs source code and now it works for me.

Give it a try.

RabbitMQ.zip

[bwyyoung]

Ok Thank you. I will try it later. Closing this issue now.

Can you tell me what exactly did you do? Your uploaded files work fine for me but if I try to compile it by myself I always get an error when building in Unity.

[auusi9]

Sorry for the long delay. I forked the project and uploaded the code that I compiled to make it work. You can check it out here: https://github.com/auusi9/Unity3D.Amqp
