Steps to reproduce:
1. Create a scheduled events with special characters (e.g. ä, ü, ...) in its title for a Extron SMP series capture agent
2. Wait until the capture agent tries to upload the event
Opencast returns a HTTP 500 upon POST /ingest/ingest which causes the recording not to be correctly ingested (we also saw SMPs trying to retransfer)
Extron SMP should work as expected with Opencast 6.x
Workaround (if any):
Don't use special characters in metadata of scheduled events
We have verified this for Extron SMP series capture agents. No idea whether others are affects.
[UPDATE] Originally thought that this would be caused by MH-13263, but the problem still appears without MH-13263.
