[Bug]: auth-credentials-json missing

[julien-alpaca]

What happened

Deploying Nessie helm chart in k8s with the following configuration:

    gcs:
      # Global GCS settings. Can be overridden on a per-bucket basis below.
      defaultOptions:
   
        # -- The authentication type to use. Valid values are: NONE, USER, SERVICE_ACCOUNT,
        # ACCESS_TOKEN, APPLICATION_DEFAULT. The default is NONE.
        authType: SERVICE_ACCOUNT

        # -- The Google Cloud service account key secret. This is required when authType is USER or
        # SERVICE_ACCOUNT.
        authCredentialsJsonSecret:
          # -- The secret name to pull a valid Google Cloud service account key from.
          name: gcs-credentials
          # -- The secret key storing the Google Cloud service account JSON key.
          key: service_account.json

I checked that secret exists in the same namespace. I can see the env variables when I exec in the pod. Pod is running but failing with:

Readiness probe failed: HTTP probe failed with statuscode: 503

and logs show:
