src/notificationHandler.ts(24,75): error TS2503: Cannot find namespace 'FirebaseFirestore'.

[burf2000]

I have spent the last hour trying to get this to run, following the other issue reports and now I get:

I think firebase has changed? if I update notificationHandler.ts to use a lowercase firebase.firestore
it compiles but then I get a package.json issue

Running command: npm --prefix "$RESOURCE_DIR" run build

> build
> tsc --skipLibCheck

src/notificationHandler.ts(24,75): error TS2503: Cannot find namespace 'FirebaseFirestore'.

Error: functions predeploy error: Command terminated with non-zero exit code2
