Speech to Text V2 streams die when I open multiple streams simultaneously

[Slavik]

I'm running speech-to-text stream on a express.js server to get real time transcription for phone calls. I have tried both speech-to-text V1 and V2. The V1 works smoothly.  However the V2 streams throw the following exception when there are any stream running at the same time.  Is there any restriction on V2?

Thanks.
