Does this issue impact your ability to continue to work with the product?
-------------------------------------------------------------

It might break existing automation

Is there any workaround available to the best of your knowledge?

-------------------------------------------------------------

Yes - listing the buckets via S3 still works

Can this issue be reproduced? If so, please provide the hit rate

-------------------------------------------------------------

Yes - reproduced on three 4.18 clusters thus far

Can this issue be reproduced from the UI?

-------------------------------------------------------------

N/A

If this is a regression, please provide more details to justify this:

-------------------------------------------------------------

Yes - the mcg-cli command works when ran against a 4.17 cluster, even when using the mcg-cli binary from 4.18.

Steps to Reproduce:

1. Download the MCG CLI via `oc extract`:

$ oc image extract --registry-config  $MY_PULL_SECRET_PATH quay.io/rhceph-dev/mcg-cli:4.18.0-47 --confirm --path /usr/share/mcg/macosx/noobaa:$MY_LOCAL_MCG_CLI_DIR 
$ chmod +x $MY_LOCAL_MCG_CLI_DIR/noobaa
$ mv $MY_LOCAL_MCG_CLI_DIR/noobaa $MY_LOCAL_MCG_CLI_DIR/mcg-cli

2. Attempt to list the buckets via the MCG CLI:

$ mcg-cli bucket list

The exact date and time when the issue was observed, including timezone details:

-------------------------------------------------------------

11/11/24, 10:00 UTC

Actual results:

-------------------------------------------------------------

The buckets were not listed due to an INVALID_SCHEMA_PARAMS error

Expected results:

-------------------------------------------------------------

The list of the buckets on the system, including at least first.bucket on a fresh installation
