To make a server-server interact with a Google API in development I need to put my service-account JSON key in the root of myapp, set
ENV["GOOGLE_APPLICATION_CREDENTIALS"] = "api-test-key.json"
and all is good.
But in production on Heroku there are config vars and the google_auth credentials_loader.rb insists on a file.
I managed to put the JSON's contents in a heroku config var nicely and can get it by calling
puts ENV["GOOGLE_APPLICATION_CREDENTIALS"]
What to do?
There is this question where they figured out a workaround but that is for oauth2 not for service-account type JSON:

We config our GoogleAPI credentials via the application.yml file ... found in the root/config/application.yml file.
In it we have;
AUTH_URI: https://accounts.google.com/o/oauth2/auth
CLIENT_SECRET: xxxxxxx
TOKEN_URI: https://accounts.google.com/o/oauth2/token
CLIENT_EMAIL: xxxx
REDIRECT_URIS: http://localhost:3000/signin/connect
CLIENT_X509_CERT_URL: https://www.googleapis.com/robot/v1/metadata/x509/901506026811-q0am03i585627ptu5r38o7cpkt8pk98l@developer.gserviceaccount.com
CLIENT_ID: xxx
AUTH_PROVIDER_X509_CERT_URL: https://www.googleapis.com/oauth2/v1/certs
JAVASCRIPT_ORIGINS: http://localhost:3000
PLUS_LOGIN_SCOPE: https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/plus.circles.read
You could maybe load in your config settings here?
