Webhook called from Bot not working

Hi, I have a BOT trying to call a webhook and I keep getting the error shown below. I have some logging at the destination of that endpoint that does not register that any connection is even hitting it. Any thoughts?

<note that Iโ€™ve replaced some sensitive information with the text omitted and changed some of the parameter values>

Error:
"Webhook HTTP post request failed with exception The underlying connection was closed: The connection was closed unexpectedly. "

In this case your target host was requiring an additional header, User-Agent.

I debugged this case first by trying to hit your end point with Postman and ensuring that works.
Then I identified it using https://requestbin.com/ and hitting that url with both Postman and the AppSheet automation and identifying what are the differences in the request. Eventually it came down to a header in this case.

I hope that helps if you encounter such errors in the future.

Thank you so much Dan!
