Build failed: function.js does not exist yarn berry

[prabhav-mehra]

Hi all, every since moving to yarn berry (3.6.4) I am facing issues with deploying functions.

Using "firebase-tools": "^13.6.0" "firebase-admin": "12.0.0", "firebase-functions": "^3.13.1",

My entry point in package.json:

"main": "lib/functions/src/index.js",

This exist and is created properly.

firebase.json

"functions": {
    "predeploy": [
      	"npm --prefix \"$RESOURCE_DIR\" run build"
    ],
	"ignore": [
		".git",
		".runtimeconfig.json",
		"firebase-debug.log",
		"firebase-debug.*.log",
		"node_modules",
		"**/.yarn/*",
		"!.yarn/patches",
		"!.yarn/plugins",
		"!.yarn/releases",
		"!.yarn/sdks",
		"!.yarn/versions"
    ],
    "source": "functions"
  },

I didn't have to ignore these files initially but ever since moving to new yarn I have exclude these files else my package size is 160mb and it throws

Error: 400, <?xml version='1.0' encoding='UTF-8'?><Error><Code>EntityTooLarge</Code><Message>Your proposed upload is larger than the maximum object size specified in your Policy Document.</Message><Details>Content-length exceeds upper bound on range</Details></Error>

After excluding my package is 1.48kb but then it fails with

Build failed: function.js does not exist.

My entry point is pointing to the correct index.js file tho.

Added "ls -l \"$RESOURCE_DIR/lib/functions/src\"" and can see the index.js file

cmd: yarn firebase deploy --project default --non-interactive --force

when I try yarn serve "serve": "$npm_execpath run build --watch & firebase emulators:start --only functions --project default"

I get an error and processes to start emulator.
