Whilst deploying a previously working mojo spec I get the following error:

Using juju 1.24.7
This error occurs when 'juju run' fails, but returns a success code. This has been seen to happen in situations like out of memory, disk space on the unit. While this is a juju bug, it won't be fixed for 1.24.7. Best I can do is catch the error and report the unit as failed.
