Google Cloud Service key JSON should not be encoded in base64 using custom image

[m-nakamura145]

I wanted to use the custom image hosted on the GCR as the base image of CircleCI 2.0.
so, I saw this document and created service account JSON key file.

When I encoded JSON key file in base64 and set the encoded text to GCLOUD_SERVICE_KEY environment variable. CircleCI build faild due to Unable to parse json key

But, When I set raw JSON text to GCLOUD_SERVICE_KEY environment variable. CircleCI build succeeded!

version: 2
jobs:
  deploy-job:
    docker:
      - image: gcr.io/project/image-name
        auth:
          username: _json_key  # default username when using a JSON key file to authenticate
          password: $GCLOUD_SERVICE_KEY  # encoded service account you created

In this sample yaml file. I think password value should be raw JSON text. Is it wrong?
