3. Check for typos or syntax errors: Ensure that there are no typos or syntax errors in the code where the mergeMap$ operator and the readFile function are being used. Even a small mistake can result in the functions not being recognized.
4. Review the Firebase documentation: Consult the official Firebase documentation or relevant resources to understand the correct usage of the mergeMap$ operator and the readFile function within Firebase service functions. Look for any specific guidelines or examples provided by Firebase.
