Firebase functions missing config json - firebase

Question

I've been away from firebase for about 2 years and just got back trying to fix couple of things in my firebase-functions. There was a plenty to update with my packages, but I got to the point where I am not sure what to do next to deploy the fixed function.
Here is the error that happens after trying to deploy a function in terminal:
lukasstateczny#Lukass-MacBook-Pro admin-pukinn % firebase deploy --only functions:mpiEnrollment
=== Deploying to 'pukinn2'...

Tried to lint /Users/lukasstateczny/Desktop/Pukinn/admin-pukinn/functions/src/index.ts but found no valid, enabled rules for this file type and file path in the resolved configuration.

Now the config folder exists, but there is no file with this name. Also I'm not sure about these weird numbers after the app name, but I guess it's probably something like a cashed file. I don't know at this point how to get this file and what values should be in it.
ANSWER: After a few helpful comments I realize I was missing serviceAccount.json file that can be found in Firebase Console -> App Settings -> Service Accounts [Tab]
I thought first firebaseConfig was enough but I was wrong.
Also couple of dependencies were outdated, so I needed to upgrade that as well, but after including the .json file the deployment was smooth as ever.
Service account template in case you are not sure how it should look:
{
"type": "service_account",
"project_id": "yourProjectName",
"private_key_id": "...a89fds980asddfs890dsa...",
"private_key": "-----BEGIN PRIVATE KEY-----\n...ahjk8123hdjak91hjkdsa...\n-----END PRIVATE KEY-----\n",
"client_email": "firebase-adminsdk-0000f#yourProject.iam.gserviceaccount.com",
"client_id": "...1234567...",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/000/firebase-adminsdk-0000%40yourproject.iam.gserviceaccount.com"
}
Obviously make sure not to share real values with anyone.

I would try removing your .firebase folder which may contain a very old hosting cache file and retry the deployment if you are able to build the app locally just fine.
Additionally, prior to deploying those functions, I would verify in development that they are working as you intend using your Functions Emulator. In the React client you obviously need to use the connectEmulator function for development to be able to test you functions if you haven't already.
You also may want to go inside your functions folder, remove the build folder, run npm run build and ensure your functions are building just fine.
