Bolt AOT issues with WebGL

Unity Engine
1

Trying to get my game building properly for the web, it includes a combination of C# and Bolt scripts. I have run Bolt’s AOT prebuild functionality which runs successfully without an error, I can confirm that the stub files are successfully created and populated.

When the game is built and run in the browser however, none of the Bolt logic actually works and the following error appears in the browser console:

27c0a33d-1fb2-4693-8183-57b1fbb40a0c:8 ExecutionEngineException: Attempting to call method ‘Ludiq.InstancePropertyAccessor`2[[UnityEngine.UI.Graphic, UnityEngine.UI, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null],[System.Boolean, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]::.ctor’ for which no ahead of time (AOT) code was generated.

Project is running 2019.4.4f1 and Bolt version 1.4.12

Thanks!

Trying clearing AOT prebuild first under Tools/Bolt/Clear AOT Pre-Build and then do AOT prebuild again. Sometimes that helps.

Also have similar issues with Bolt and WebGL:

Attempting to call method 'Ludiq.StaticActionInvoker`

Also getting:
MethodAccessException: Attempt to access method ‘Ludiq.IGraphData.TryGetElementData’ on type ‘’ failed.

(Filename: currently not available on il2cpp Line: -1)

A rebuild of AOT doesn’t fix these issues.

Has anyone perhaps tried the 2.0 Alpha version of Bolt?

Are any of you using generic lists? Bolt requires you to stick with AOT types for collections on AOT platforms - AoTList and AoTDictionary.
