Why do I get credential read in error on google slide API?

Question

I downloaded the gsuite developers python code from :

(https://github.com/gsuitedevs/python-samples)

I then enabled api access and downloaded the credentials.json file and ran the quickstart.py in:

(python-samples-master/slides/quickstart) and it worked and outputted

The presentation contains 5 slides:
- Slide #1 contains 4 elements.
- Slide #2 contains 11 elements.
- Slide #3 contains 9 elements.
- Slide #4 contains 5 elements.
- Slide #5 contains 12 elements.

So it worked. Then I tried to run test_snippets.py in:

(python-samples-master/slides/snippets)

And I get an error

======================================================================
ERROR: setUpClass (__main__.SnippetsTest)

During handling of the above exception, another exception occurred:

I definitely have a GOOGLE_APPLICATION_CREDENTIALS that points to the same credentials that successfully ran quickstart.py.

Is there something else I need or do I need to change some code to load the credentials data in?

It seems like GoogleCredentials.get_application_default() call is the one that is erroring

    def create_credentials(cls):
        credentials = GoogleCredentials.get_application_default()
        scope = [
            'https://www.googleapis.com/auth/drive',
        ]
        return credentials.create_scoped(scope)

The file pointed to the environment variable GOOGLE_APPLICATION_CREDENTIALS is not a valid service account json file.

Open your service account json file. The beginning of the file should look similar to this:

{
  "type": "service_account",
  "project_id": "development-123456",
  "private_key_id": "19c38bac6560abcdef01234567ac4da7991cbaad",
  "private_key": "-----BEGIN PRIVATE KEY-----\nMIIEvQIBADANB

Ok, yes, I just got a new service account json file and the format looks like the one you posted with some other information as well. – Mike Mar 14 '19 at 00:19
