DOTFILE.RC.read() fails despite file bring created

[programmer24601]

Expected Behavior

When logging in with custom credentials I am able to run clasp pull/push/run successfully.

Actual Behavior

When attempting to log in with custom credentials I receive:

Authorization successful.

Local credentials saved to: ./.clasprc.json.
Be sure to never commit this file! It's basically a password.
Could not read API credentials. Are you logged in globally?

The .clasprc.json file is created and contains what looks to be the correct content.

Steps to Reproduce the Problem

1. Follow instructions here: https://github.com/google/clasp/blob/master/docs/run.md
2. Add creds.json file to project of this structure:
   { "installed": { "client_id": "asdf.apps.googleusercontent.com", "project_id": "asdf", "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_secret": "asdf", "redirect_uris": ["urn:ietf:wg:oauth:2.0:oob", "http://localhost"] } }
3. Run clasp login --creds creds.json
4. Authorize in browser.
5. clasp login --status returns:

You are not logged in.

Please note that the regular method of logging in (clasp login) is successful.

Debugging shows that dotfile_1.DOTFILE.RC = {exists: ,read: ,write: ,delete: }
