Hi Edward An,

It seems like the error consistently occurs in your HttpStart function due to an undefined extraInputs property. To troubleshoot:

1. Review the index.js file of HttpStart for extraInputs references.
2. Verify correct function parameters passed to getClient.
3. Check the durable functions library docs for usage changes.
4. Ensure function bindings handle extraInputs properly.
5. Add logging to track variable values.
6. Investigate recent code changes.
7. Monitor Azure Function logs for additional clues.

This approach should help pinpoint and resolve the issue. Let me know if you need further assistance!
