0.74: Int32 | null generates Nullable Integer on java side, but Ljava/lang/Double on c++ side.

[mfazekas]

In RN 0.74 we started to see Error: Exception in HostFunction: no non-static method "Lcom/rnmapbox/rnmbx/components/mapview/NativeMapViewModule;.setHandledMapChangedEvents(Ljava/lang/Double;Lcom/facebook/react/bridge/ReadableArray;Lcom/facebook/react/bridge/Promise;)V

We implement the function as

    typealias ViewRefTag = Int
    ...
   override fun setHandledMapChangedEvents(
        viewRef: ViewRefTag?,
        events: ReadableArray,
        promise: Promise
    ) {

Codespec: Int32

Our maps/src/specs/NativeMapViewModule.ts has:

setHandledMapChangedEvents: ( viewRef: Int32 | null,  events: ReadonlyArray<string>) => Promise<Object>; 

specs-generated.cpp: java.lang.Double

Codegen generated cpp: android/build/generated/source/codegen/jni/rnmapbox_maps_specs-generated.cpp has Ljava/lang/Double

static facebook::jsi::Value __hostFunction_NativeMapViewModuleSpecJSI_setHandledMapChangedEvents(facebook::jsi::Runtime& rt, TurboModule &turboModule, const facebook::jsi::Value* args, size_t count) {
  static jmethodID cachedMethodId = nullptr;
  return static_cast<JavaTurboModule &>(turboModule).invokeJavaMethod(rt, PromiseKind, "setHandledMapChangedEvents", "(Ljava/lang/Double;Lcom/facebook/react/bridge/ReadableArray;Lcom/facebook/react/bridge/Promise;)V", args, count, cachedMethodId);
}

ModuleSpec.java: java.lang.Integer

Codegen generate-specs-cli.js generated maps/android/src/main/old-arch/com/rnmapbox/rnmbx/NativeMapViewModuleSpec.java has as:

public abstract void setHandledMapChangedEvents(@Nullable Integer viewRef, ReadableArray events, Promise promise); 

See rnmapbox/maps#3527

This looks like a bug. Can you open an issue on facebook/react-native with "Type: New Architecture".

Also is this a regression from 0.73 to 0.74? @mfazekas
