project_domain_delete_required with HTTP 409. Repeating the same request unchanged does not help.
What to do
This project still has a live or pending custom-domain connection. Read ‘ohmyhost domain paid status —project ULID —json’, remove that connection with ‘ohmyhost domain paid delete —project ULID —hostname HOST —yes —json’, then create a fresh project deletion plan. Repeating while it remains connected cannot work. If the steps above do not resolve it, report it with therequest_id from the error.
