Get Record component only working intermittently for Firestore database documents

Hello fellow Appgyvers!

I am currently experiencing a problem where my Get Record component which gets data from several Firestore database documents is only working intermittently!

Very frustrating! Within making several Get Record Requests to my Firestore database (Get Record request looping several times) - sometimes the Get Record request works and other times it does not.

I am getting the following error:
"JSON error response from server: {"error":{"code":401,"message":"Request had invalid authentication credentials. *
*Expected OAuth 2 access token, login cookie or other valid authentication credential. See\“,\“status\”:\“UNAUTHENTICATED\”}}.”

Is anybody else experiencing a similar problem?

Can anybody help me?
