Troubleshooting WebSocket Connection Errors in Deepgram Python SDK

When working with Deepgram's Python SDK for live transcription, users may encounter WebSocket connection errors, such as a server-rejected connection with HTTP 400 status codes. These errors can disrupt the transcription process. Here's how to troubleshoot and resolve this issue.

Understanding the Problem

A WebSocket connection error usually indicates issues with the request sent from the client to Deepgram's servers. This could be attributed to mismatched parameters, incorrect API key usage, or a deprecated SDK version.

Steps to Resolve

Update the SDK:
- Ensure you are using the latest version of the Python SDK. Deepgram's SDK versions update frequently, fixing bugs and improving functionality. Upgrading to the latest version can resolve compatibility issues.
- You can update the SDK by using the package manager:
```
pip install deepgram-sdk --upgrade
```
Verify API Key:
- Confirm that the API key in your environment variables is valid and has the necessary permissions for transcription.
Correct Parameters:
- Ensure all the parameters in the options dictionary match Deepgram's documentation for live transcription, specifically match encoding, sample rate, and model specifications.
Check API Endpoint:
- Verify that your API endpoint URL is correct. For WebSocket connections, it should be wss://api.deepgram.com/v1/listen.
Network Issues:
- Ensure your network configurations allow WebSocket connections and that no firewall settings are blocking the connection.
