Context server not found

Error message

Context server not found

What it means

Emitted by show_modal_for_existing_server when no settings entry exists in ProjectSettings.context_servers for the given server id and no built-in descriptor is registered in the ContextServerDescriptorRegistry. The requested context server configuration cannot be located anywhere, so there is nothing to open the edit modal for; the offending input is the server_id passed to the modal.
