circles Could not change the member level to

Hi, from cantacs, opening a circle, i add a member (ldap user account). Now try to promote user to any of the other levels (Admin, Moderator or sole owner) the interfa dispplay this error:

Could not change the member level to ...

the command ./occ circles:check give:

Checking loopback address.

. The loopback setting is mandatory and can be checked locally.
. The address you need to define here must be a reachable url of your Nextcloud from the hosting server itself.
. By default, the App will use the entry 'overwrite.cli.url' from 'config/config.php'.

• testing current address: https://______/

• GET request on https:/_______/index.php/csrftoken: 200
• POST request on https://___________/index.php/apps/circles/async/test-dummy-token/: 200
• Creating async FederatedEvent af250b21-5811-4a82-a364-9a6b5e9976f6
• Waiting for async process to finish (5s)
• Checking status on FederatedEvent verify=17 manage=42

• Loopback address looks good

i have also modified config file to include the trailing slash into overwrite.cli.url , but same result.

nextcloud version is: 23.0.2
circles version: 23.0.1

Nextcloud log file give this:

Start with apps/circles/lib/FederatedItems/MemberLevel.php at line 111 and trace the reported PUT through FederatedEventService.php, MemberService.php, and LocalController.php. Reproduce changing an LDAP member's level and verify that Admin, Moderator, and sole-owner promotions complete without the reported “This level cannot be edited” error.
