Cannot iocage list due to dataset not found

I did install the Zoneminder plugin.

It was not working at some point (mysql auth error in the jail), so I wanted to delete it. It was running for ages, then I got disconnected.

Now when I want to 'iocage list', I have the following error due to the dataset not present.
 

% sudo iocage list
