has empty mandatory "short_message" field

[soloam]

Hello, I'm having some errors on my graylog input from the home assistant addon:

2026-05-28T15:04:19.610+01:00 ERROR [DecodingProcessor] Error processing message RawMessage{id=1ef7e090-5a9e-11f1-b169-861670b698d2, messageQueueId=1731622687, codec=gelf, payloadSize=302, timestamp=2026-05-28T14:04:19.609Z, seqenceNr=12916, remoteAddress=/192.168.2.51:52829}

Some messages are arriving without mandatory short_message field...

Do you know what it is?

Thank you

I will have a look this weekend.

Do you know if this started after upgrading to the latest version (1.11.0) which I released last weekend?

this the max I can go... it's the last log file... and is from 13-05-2026

This was the result of empty lines. It should be fixed in today's release, 1.12.0
