Google Cloud S3 & rclone: Error 400: Cannot insert legacy ACL for an object when uniform bucket-level access is enabled

  • 772

I'm trying to configure rclone to access a google cloud bucket (which happens to be managed by terra.bio. My rclone config reads as follows:

[terra]
type = google cloud storage
object_acl = private
bucket_acl = private
token = {"access_token":"XXXXX","token_type":"Bearer","refresh_token":"XXXXX","expiry":"XXXXXX"}

I've tried setting authenticatedRead and private but get the same result.

The error message I see is:

2022/08/13 18:24:44 Failed to copy: googleapi: Error 400: Cannot insert legacy ACL for an object when uniform bucket-level access is enabled. Read more at https://cloud.google.com/storage/docs/uniform-bucket-level-access, invalid

  1. The solution, thanks to @John Hanley in comments, is here: https://github.com/rclone/rclone/issues/3644

    Either of the following solves the problem:

    Set an environment variable:

    export RCLONE_GCS_BUCKET_POLICY_ONLY=true

    Or use the rclone param:

    rclone --gcs-bucket-policy-only copy localfile gcp:bucket/path/
