Comment 18 for bug 2056193

I've just tried to run another action on a different charm in this model to see what happens, in case that's helpful:

```
prod-httprequest-lego-provider-k8s@is-bastion-ps6:~$ juju run nginx-ingress-integrator/0 get-certificate
Running operation 13 with 1 task
  - task 14 on unit-nginx-ingress-integrator-0

Waiting for task 14...
ERROR the following task failed:
 - id "14" with return code 1

use 'juju show-task' to inspect the failure

prod-httprequest-lego-provider-k8s@is-bastion-ps6:~$ juju show-task 14
prod-httprequest-lego-provider-k8s@is-bastion-ps6:~$
```

The failure is expected because I didn't pass a parameter that it needs (we need to update the charm to make that a required parameter).
