Description

Suddenly I got this error message when I play the app.

NotSupportedException: To marshal a managed method, please add an attribute named 'MonoPInvokeCallback' to the method definition. The method we're attempting to marshal is: Mediapipe.Unity.OutputStream`2[[Mediapipe.NormalizedLandmarkListPacket, Mediapipe.Runtime, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null],[Mediapipe.NormalizedLandmarkList, Mediapipe.Runtime, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]]::InvokeIfOutputStreamFound

And this is the definition of InvokeIfOutputStreamFound of OutputStream.cs file (Nothing changed to your code)

  [AOT.MonoPInvokeCallback(typeof(CalculatorGraph.NativePacketCallback))]
    protected static Status.StatusArgs InvokeIfOutputStreamFound(IntPtr graphPtr, int streamId, IntPtr packetPtr)
    {
      try
      {

I can’t get the idea, so could you tell me something suspicious about it?

I have the same problem. Setting IL2CPP code generation to Faster (smaller) builds makes this issue.

Did you remove the cache (e.g. Library/) before starting UnityEditor?
