Issue descriptionIssue description

When editing the ACL configuration of the Object Storage bucket, you get this error message:

message: Access Denied;
status: undefined;
description: Access Denied;
code: GATEWAY_REQUEST_ERROR;
Request ID: undefined;
Trace ID: undefined;

SolutionSolution

The Access Denied error most often occurs due to a poorly configured access policy. To edit the ACL configuration of the bucket, you need the storage.admin role.

Make sure the Resource field within the access policy contains these two values: bucket_name/* and bucket_name/.

If the issue persistsIf the issue persists

If the above actions did not help, create a support ticket. Provide the following information in your ticket:

  1. Object Storage bucket name.
  2. Screenshot or full text of the error message.
