Firebase deploy error - Configuring expiration modes is not permitted

Question

I'm trying to deploy my firebase project but I'm getting this error:

HTTP Error: 400, Configuring expiration modes is not permitted

I haven't found anything on web and I don't know what could it be.

Anyone has encountered the same error?

Thanx

Posting the @ProfLayton's solution as a Community wiki for better visibility.

The error has been fixed by launching the deployment scripts separately:

1. npm run build = REACT_APP_ENV=PROD GENERATE_SOURCEMAP=false react-scripts build
2. firebase use [proj-name]
3. firebase deploy --only functions
4. firebase deploy --only hosting:prod
