Some events can´t be deleted in Admin-UI

[andreas schiefner]

Hi everyone,

We have encountered an issue with opencast-13.2.0 where some events can´t be deleted in the admin-UI.

In the UI i can see that after i ran the delete-workflow theres still an publication on engage.
When i click to watch the video on the engage-player (paella) the video can´t be loaded.

Furthermore the event still holds two attachments: security-policy-episode & security-policy-series.

If i re-run the delete-workflow i can see the following in the logs:
```
2024-04-09T12:32:36,708 | WARN  | (RetractionListener:63) - The retract workflow "Delete" (id: 589147, created by: <user>, media package c127ccd2-be77-415b-8f6a-577d43f89956) has some non-retracted publications, refusing to orphan them.
```

This only happens with some events/videos. To me it looks like the two attachements are not deleted properly and cause this event to be stuck in the admin-ui.

Seems to be kinda the same issue like:

Does anyone have insights or ideas regarding this issue?

Thanks in advance for your help!

Best regards

Hi,

I guess this problem is related to https://groups.google.com/a/opencast.org/g/users/c/adwm2TEjTTI/m/Jkt_alVMAQAJ.

Also, do you have other warnings further above related to engage (might also be in the log of a different node)? It's odd that that is left over, since that should be retracted by the delete workflow. Maybe there's a problem...

Cheers,

Katrin

Thanks all for your help, appreciate it!

Adding this did the trick, like Dietmar mentioned:
```
 <!-- Here you can place operations to retract publication from your publication channels -->
<operation
  id="retract-configure"
  exception-handler-workflow="partial-error"
  description="Retract event from external api publication channel">
  <configurations>
<configuration key="channel-id">api</configuration>
<configuration key="retract-streaming">false</configuration>
  </configurations>
</operation>
```
