Random drops when using STT (JavaScript)

See original GitHub issue

Describe the bug For my use case, I need to convert both sides of a video call to text. For the mic, I am using the SDK’s mic recognition. For the speaker, I am using the MediaStream API.

I use continuous async recognition on both sides.

Completely randomly, I see drops in the STT (on both mic & speaker streams). The error message is

{
  privSessionId: 'F181283623C54E55AF77F6018A7D8FA7',
  privReason: 0,
  privErrorCode: 3
}

Please note that the error details field is undefined here.

As per the documentation, this is due to too many requests. But we’re on a paid tier and should not have this issue (I think).

Separately, if I try to restart the recognition, I see the following error

{
    "privSessionId": "9AC4B13654CE431BA7C0EAF39209DBA0",
    "privReason": 0,
    "privErrorDetails": "Validation failed with status: TooManyRequests websocket error code: 1007",
    "privErrorCode": 2
}

Which should be for “BadRequestParameters” but the error details lists “TooManyRequests”.

I’m try to figure these questions out & would appreciate inputs:

why are these drops happening randomly?
why does there seem to be disparity in the error messages?

To Reproduce Steps to reproduce the behavior:

start mic recognition
immediately start a new stream based recognition (capturing data from the speaker)

Expected behavior Multiple streams return data without dropping.

Sorry, need to update my last comment. I was not testing with two separate keys. Doing so now.

I’ll post an update here soon.

Thanks @glharper . The app is deployed across many users so will have to centralize the counting.

Will test with 1.19.0 and raise an issue if it comes up.

Closing the issue for now. Thanks for all the help!
