prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  We should disable the remap_user_ids command for the time being
  We have changes on Staging that need to make their way to Production soon.
  
  The `remap_user_ids` command is not working properly (#1165).
  
  We should disable the command for now so we can deploy recent changes to Production.
