Due to an issue during index rebuild, I am dealing with some events without any workflows right now. While debugging the problem, I came across some strange behavior in the admin ui:

First, the event's workflows tab shows an empty list:

This is expected, as the corresponding request to Opencast failed:

GET https://opencast.example.com/admin-ng/event/c7648b1a-42e1-4df2-9dc2-9b23d4daaced/workflows.json

"url":"/admin-ng/event/c7648b1a-42e1-4df2-9dc2-9b23d4daaced/workflows.json",
"status":"500"
}

But, after displaying another event's details and returning to the original event, that other event's workflows are suddenly shown:

I guess having events without any workflows attached should be quite uncommon, but displaying another events' workflows probably should not happen in any case and may indicate a bug somewhere in the admin ui?

There is a workflow cleanup service IIRC. So, it could be the case that older workflows are deleted. Not sure if that is commonly activated.

In any case, a 500 due to a NPE should not happen.

There is a workflow cleanup service IIRC. So, it could be the case that older workflows are deleted. Not sure if that is commonly activated.

I guess I found the root cause: The workflows still exist in the system but in "paused" state, therefore have been ignored/skipped by the index rebuild, and could not be found by the admin ui (stopping the workflows and re-building the index fixed the issue).

In any case, a 500 due to a NPE should not happen.

So you suggest this is not only a "cosmetic" issue in the admin ui, but a problem in Opencast?

Here is the full admin node log of the 500 response:
