I’m getting this error that can’t be resolved after dozens of attempts

Error: Firebase Admin SDK initialization failed: The FIREBASE_SERVICE_ACCOUNT_KEY_JSON_BASE64 environment variable is not set.

Try asking Gemini for instructions when it fails to fix an error by itself. By explicitly asking for instructions, you may find there is a step or two Gemini couldn’t execute on it’s own and needs for the developer to take manual action on. Give this a try and let us know how it works out.

"Error: Firebase Admin SDK initialization failed: The FIREBASE_SERVICE_ACCOUNT_KEY_JSON_BASE64 environment variable is not set.

Provide me with very detailed and easy to follow step-by-step instructions for how to resolve this error.
