Fix Plan

The issue seems to be related to an invalid URI scheme when trying to connect to the gpt-1.5-realtime via Azure. To fix this, we need to ensure the URI scheme is either ws or wss.

Step-by-Step Solution

  • Check the url variable in the _realtime_health_check function to ensure it starts with either ws or wss.
  • Update the url to use the correct scheme. For example:
url = "wss://example.com/openai/realtime?api-version=2024-10-01-preview&deployment=gpt-realtime-1.5"
  • If the url is constructed dynamically, ensure the scheme is set correctly. For example:
scheme = "wss"
url = f"{scheme}://example.com/openai/realtime?api-version=2024-10-01-preview&deployment=gpt-realtime-1.5"

Verification

To verify the fix, attempt to connect to the gpt-1.5-realtime via Azure again and check the log output for any errors. If the connection is successful, the log output should not contain any errors related to the URI scheme.

Extra Tips

  • Ensure the Azure provider is configured correctly and the gpt-1.5-realtime deployment is available.
  • Check the LiteLLM documentation for any specific requirements or restrictions on connecting to the gpt-1.5-realtime via Azure.
