firebase-debug.log

The function is working fine until I use initializeApp(). ( I also created a database in Firestore)

When I run npm run serve, I get this error: "Failed to load function definition from source: FirebaseError: Functions codebase could not be analyzed successfully. It may have a syntax or runtime error."

And when I remove initializeApp(), the function is served without any issue.

I am using Windows 11.
Node 20.19.2.
firebase-tools 14.8.0
