A few days ago, #1 was merged, and the compile script uses the syntax ${GOOGLE_CREDENTIALS@Q} which was introduced in bash 4.4.

The heroku-16 stack has bash 4.3.48, so this buildpack no longer works there (but on heroku-18 it works fine).

During compile phase, when I read google-credentials.json, the file is empty. After further reading I found out that google-credential.sh only contain echo > /app/google-credentials.json.

Referencing Build Pack API Documentation, turns out build pack should have read env value from $ENV_DIR instead from env directly.

#3

cat google-credentials.json

Empty.

heroku-20

Hi,
I have a add the two variables GOOGLE_CREDENTIALS and GOOGLE_APPLICATION_CREDENTIALS.

I am getting this error:

google.auth.exceptions.DefaultCredentialsError: ('File google-credentials.json is not a valid json file.', JSONDecodeError('Expecting value: line 2 column 1 (char 1)',))

my json file looks like this:

{ "type": "service_account", "project_id": "324", "private_key_id": "4edf183b0221", "private_key": "-----BEGIN PRIVATE KEY-----\nMIIEvgIBADANBgkqhSkAgEAAoIBAQC3z3HICSRreEIv\nV3v0O4j/N+vjhmLrSpAXaeLHAkFk/RsYmzR\neHiRSTtP0YFfxAXzLsDAN82z5cWY\ny4p0QuNro8685K73P\n-----END PRIVATE KEY-----\n", "client_email": "starting.com", "client_id": "114229", "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/x509/sa.gserviceaccount.com" }

Thank you

Hello, I followed the instructions on how to install the buildpack, but I get this error in the heroku console when I try to invoke google cloud storage functions:

I ran $ heroku run cat google-credentials.json and the output was empty:

What should I do to debug this problem? Thank you so much!

what is with the ENVVAR name here having @Q at end? it is very random seems to have come from the last PR merge.
