/admin-ng/resources/events/filters.json results in 500 error

[Rillke]

We occasionally see that /admin-ng/resources/events/filters.json results in 500 server error with stack trace below. When this happens, Opencast usually does not recover unless we restart the admin container (OC 19).

When it works, /admin-ng/resources/events/filters.json is about 1,3 MB is size.

What's causing our admin server to assume it has no provider for organisation <mh_default_org> with the name SERIES ?
