When a project is shared, two users can be viewing and making changes to the same pipeline. If you are working with a segment in the pipeline, another user can delete the pipeline. When this happens, you are notified that the pipeline is deleted. You can still view the segment, but you get this message when trying to make any changes.
The
requested resource was not found. Check the application’s error
logs or contact your system administrator for assistance.The pipeline no longer exists. Exit the segment and the modeling node.
