Error: cannot call send() while not connected

[AI-General]

Hello,

I am using this code for my project but met following error.

Error: cannot call send() while not connected

Error occures in following code snippet:

deepgram.addListener(LiveTranscriptionEvents.Close, async () => {
console.log("deepgram: disconnected");
clearInterval(this.keepAlive);
deepgram.finish(); <-- HERE -->
});

This is log:

    throw new Error('cannot call send() while not connected');
          ^

Error: cannot call send() while not connected
