Unfortunately the frame missing after panel_service_sync_one is the one I kind of need to fix this ,at least with the hope that it contains some details about the indicator that' it's trying to sync.

Could you please state which indicators you are using (everything on the right of the panel please), maybe I can reproduce the issue locally if it's a certain indicator causing it. Thanks.
