@ACME Mike I'm sorry to hear you're experiencing issues with the server URL not being hit consistently. It sounds like there might be a problem with how the server URL is being set for the function calls. To address this, we should ensure that the server URL is correctly configured at the assistant creation or during an assistant update. Could you please confirm if there have been any recent changes to your assistant's configuration or to the server that might be affecting the function calls? Additionally, it would be helpful to check the server logs to see if there are any incoming requests from the assistant at all, which could indicate whether the issue is with the network or the assistant's configuration. If everything seems to be in order on your end, we may need to look into this issue further. Please provide any additional details you can, and we'll do our best to resolve this as soon as possible.
