Google Memorystore Actioncable error
I have a customer in this internal Zendesk ticket running GitLab 16.8.2 and they're seeing this error from sidekiq when attempting to delete a project:
"Deletion failed on REDACTED_project_name with the following message: ERR unknown command `client`, with args beginning with: `setname`, `ActionCable-PID-826991`,"
They are using Google Memorystore version "6.X".
I found several prior issues with the same error in the past couple of years, the first was this issue in GitLab 14.6. More recently there was this one associated with gitlab-kas. I found this comment from @stanhu saying that sidekiq had dropped the use of this client command, but it seems as though maybe it's back?
