Cluster with only RRR topics gets `unexpected REST API error` and `AccessDenied` error in logs

[vuldin]

Version & Environment

Redpanda version: (use rpk version): 24.1.9

What went wrong?

In a cluster being used exclusively for RRR topics, the following error appears regularly in the logs:

Jul 01 00:00:59 cy2-rr-rp-01.aq.tc rpk[2011578]: ERROR 2024-07-01 00:00:59,913 [shard 0:main] s3 - s3_client.cc:471 - Accessing "" in none, unexpected REST API error "" detected, code: AccessDenied, request_id: , resource:

RRR topics continue to function properly.

What should have happened instead?

This error should not appear because the RRR topics continue to function properly. The issue is the cluster doesn't have an actual bucket for TS (cloud_storage_bucket: "none" per our docs), but the cluster still tries to connect to this bucket none and fails.

How to reproduce the issue?

1. enable RRR topics
2. check logs
