Multiple Library Codegens?

[iBotPeaches]

I engulfed a private library that was working an upgrade to New Arch - it has never been deployed/merged. The intending application is now 73.

So I took it for a spin with pod install and it crashed out quick with:

[Codegen] Done.
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined
    at new NodeError (node:internal/errors:405:5)
    at validateString (node:internal/validators:162:11)
    at Object.join (node:path:1171:7)
    at node_modules/react-native/scripts/codegen/generate-artifacts-executor.js:398:40

Which is probably because I have an array of libraries vs one I'm guessing:

  "codegenConfig": [
    {
      "name": "RNBluetoothSerialSpec",
      "type": "modules",
      "jsSrcsDir": "src",
      "android": {
        "javaPackageName": "com.xxx.xxx"
      }
    },
    {
      "name": "RNAcessoryManagerSpec",
      "type": "modules",
      "jsSrcsDir": "src"
    }
  ],

Though I'm looking at the original ticket where this development started and it has quoted this is a valid example:

"codegenConfig": {
        "libraries": [
          {
            "name": "libName1",
            "type": "all|components|modules",
            "jsSrcsRoot": "libName1/js"
          },
          {
            "name": "libName2",
            "type": "all|components|modules",
            "jsSrcsRoot": "libName2/src"
          }
        ]
      }

Ultimately I struggle in docs to find if this is a supported behavior now, so looking for some help. My guess is I might have to unify these libraries to 1 between iOS/Android - However, this is Bluetooth so between External Accessory on iOS and android.bluetooth.* on Android I don't see an elegant way to do that without some no-op methods on both platforms.

A bit lost as I can't find anything in the Codegen docs of the schema itself of this property.

Someone able to just set me straight?

I believe you can specify one entry for codegenConfig in package.json

  "codegenConfig": {
    "name": "AbcCGen",
    "type": "all",
    "jsSrcsDir": "src/spec",
    "android": {
      "javaPackageName": "com.abc"
    }
  },

and then put multiple specs into src/spec. Codegen will pick it up.

That's the correct answer. We used to support an array of dependencies inside codegenConfig but we moved away from it as it was divergent between Android & iOS and was complicating the codegen code
