Uncaught (in promise) TypeError: handle is undefined

[キャロウ マーク]

After fixing the raw pointer issue I asked about in another thread, a new problem has cropped up. Whenever my app tries to call a native function on the created module I get the subject error.

Here is a typical stack trace

Uncaught (in promise) TypeError: handle is undefined

    __emval_get_property http://192.168.50.139:8080/libktx.js:7

    anonymous http://192.168.50.139:8080/libktx.js line 7 > Function:9

    testCreate http://192.168.50.139:8080/libktx-webgl/libktx-test.js:802

I am using -sMODULARIZE and I instantiate the module with

  createKtxModule({preinitializedWebGLContext: gl}).then(instance => {

    window.ktx = instance;

    // Make existing WebGL context current for Emscripten OpenGL.

    ktx.GL.makeContextCurrent(

                ktx.GL.createContext(document.getElementById("glcanvas"),

                                        { majorVersion: 2.0 })

                );

    main()

  });

where createKtxModule is the export name. That call to ktx.GL.makeContextCurrent is working but I suppose that is not a native function.

Everything was working on 4.0.7.

I read https://emscripten.org/docs/compiling/Modularized-Output.html but can’t see any change required when continuing to use -sMODULARIZE.

Does anyone know how to fix this?

I am horrified by the number of breakages these supposedly minor patch releases (4.0.8 and 4.0.9) have caused in my code. I have spent 2 days on fixes so far.

I figured this one out too. I built a debug version and at run time a message appeared in the console telling me I need to add HEAP8 to EXPORTED_RUNTIME_METHODS. After doing that my apps work except for one test which is failing and which I will investigate now..
