I've got such exception in the browser console with 1.4.0 (legacy):

Error: This marker function should never been called. Looks like compiler did not eliminate it properly. Please, report an issue if you caught this exception.

How should I report this issue? There is not really much more information but I suppose it comes from serialization.

This is generated JS code:

Kotlin.getReifiedTypeParameterKType = function (typeParameter) {
    throwMarkerError();
  };
  function throwMarkerError() {
    throw new Error('This marker function should never been called. ' + 'Looks like compiler did not eliminate it properly. ' + 'Please, report an issue if you caught this exception.');
  }

Just got the same issue today, is there a workaround in the meantime? @Robert Jaros

[Robert Jaros]

I'm still using KClass<T>.serializer() with @OptIn(InternalSerializationApi::class) annotation.

[Omar Mainegra]

Thanks, let me try it

[Robert Jaros]

The issue appeared when I tried recommended migration to inline serializer() function, so I've just skipped this migration for now.

Yeah, for me it was the same, until it failed in JS (Jvm and Native work just fine)
