I just test with Postman to make sure the endpoint is working well, and it is. I have the tool connected in the "Functions" tab for the assistant, and in the prompt I instruct it to use it, and I know it's using the tool because it says the start message and the fail message. I have the Server URL set to the same URL that responds back as shown earlier in Postman. It's not set to Async, so I'd expect it to wait for the response and use the result value accordingly. Not Sure what I'm doing wrong. Is the toolCallId supopsed to be prefixed with 'call_' or no? :::scratches-head:::
