[Bug]: LiteLLM Proxy deployment to GCP Cloud Run failing when attempting to use GCS for config.yaml

[ElliotK-IB]

What happened?

Hi, I'm trying to deploy LiteLLM Proxy to GCP Cloud Run with the config.yaml set up in Google Cloud Storage (GCS) according to this documentation: 5. config.yaml file on s3, GCS Bucket Object/url.

Version: v1.76.1-stable (i.e., main-stable as of 9/16/2025)

I'm getting this error message:

LiteLLM Proxy:ERROR�[0m: load_config_utils.py:63 - Error retrieving file contents: GCS Bucket logging is a premium feature. Please upgrade to use it. You must be a LiteLLM Enterprise user to use this feature. If you have a license please set `LITELLM_LICENSE` in your env. Get a 7 day trial key here: https://www.litellm.ai/enterprise#trial.

Not sure if GCS Bucket logging and fetching the config from GCS are meant to be related. Is fetching the config from GCS a premium feature as well?

If not, any pointers on how to get this working?

I'm using a cloudbuild.yaml file, here's the relevant snippet where I'm setting the environment variables:

entrypoint: gcloud
    args:
      - 'run'
      - 'deploy'
      - '${_SERVICE_NAME}'
      - '--image'
      - '${_GCP_REGION}-docker.pkg.dev/${PROJECT_ID}/${_ARTIFACT_REGISTRY_REPO}/${_SERVICE_NAME}:${COMMIT_SHA}'
      - '--region'
      - '${_GCP_REGION}'
      - '--allow-unauthenticated'
      - '--port'
      - '4000'
      - '--set-env-vars=LITELLM_CONFIG_BUCKET_TYPE=gcs,LITELLM_CONFIG_BUCKET_NAME=${_GCS_BUCKET_NAME},LITELLM_CONFIG_BUCKET_OBJECT_KEY=${_GCS_OBJECT_KEY}'
      - '--update-secrets=GCP_PROJECT_ID=${_GCP_PROJECT_ID_SECRET}:latest,GCP_PROJECT_REGION=${_GCP_PROJECT_REGION_SECRET}:latest'
...
substitutions:
  ...
  _GCS_BUCKET_NAME: 'my_bucket_name'
  _GCS_OBJECT_KEY: 'config.yaml'
  ...

The service account has Storage Object Admin role.

Additional

• I was able to get LiteLLM Proxy running fine with config in the repo but am considering GCS for greater flexibility.
• I don't have a database or proxy master key set up yet, but those are next so I can get the Admin UI going
