Chat not working after transcript announce message recieved

[HighwayStar]

I'm using docker installation of jitsi stable-9955 with vosk transcription, JIGASI_TRANSCRIBER_ADVERTISE_URL=true

Faced strange issue:

When conference created and users connected thay could use chat wihout issue, but when moderator enables Subtitles and Announcement message appeared in chat it became broken. Users who post messages in chat cannot see its own messages, while moderator can see it.

Chat became broken on clients after such error in js console

And seems it happens only on chrome based browsers, when Firefox clients have chat working

did some tests, looks more like chat stops working on first subtitle message recieved. If I starting transcribtion with switched off mics chat works until mic enabled and subtitle message sent.

I did some js debugging, and it seem

 const language = state['features/base/conference'].conference
        ?.getLocalParticipantProperty(P_NAME_TRANSLATION_LANGUAGE);

in middleware.js function _endpointMessageReceived(store, next, action) result is undefined, and next it crashes in _getPrimaryLanguageCode()

I've tried to lunch minimal eaxample, here is my env file attached.

test.txt

starting like

sudo docker compose -f docker-compose.yml -f jigasi.yml -f transcriber.yml up

vosk container running on separate machine

I also checked with previous release 9909 and here chrome working fine, but Firefox was broken. Will try one older.
