Would Like to read Data from the Firebase Cloud Firestore. I have already created a project, and added my Rails (6.0.3) application to the fire store db via settings -> add web app. This provided me with script tags containing the firevbase SDK to add to my web application under the body tag, I did all of this. I am trying to follow the instructions @ https://firebase.google.com/docs/firestore/quickstart?authuser=0#ruby. The very first instruction reads: ''' export GOOGLE_APPLICATION_CREDENTIALS="path/to/your/keyfile.json" ''' I have already downloaded this JSON file by creating a key from the service account associated with my firebase project, this key was downloaded and placed within my project tree. However I do not know where to put Export google creds within my Rails environment? Previously I tried to insert it into environment/development.rb but the export key word is not a part of Ruby syntax.
I have already installed the cloud-firestore-gem and I have been working through this post trying to piece everything together How to connect to a Firestore database with Ruby. When I run this within the rails console:
cred = Google::Cloud::Firestore::Credentials.new("path/to/myJsonSerivcesKey.Json")
I receive this trace back :
Signet::AuthorizationError (Authorization failed. Server message:)
{"error":"invalid_scope","error_description":"Invalid OAuth scope or ID token audience provided."}
I think this error has to do with me not doing something correct when using the API key from the service account but I am not really sure. Any advice on how to correct the Invalid OAuth Scope and where to put the export GOOGLE_APPLICATIONS+CREDENTIALS would be great. Also I am not sure why Firebase SDK needs to be pasted into the body tags of the application, could someone explain what this does for the app?
