I'm trying to call an incoming webhook.

The response status code is 200, yet the message cannot be viewed in the chat.

 

The response text contains the following:
'Webhook message delivery failed with error: Microsoft Teams endpoint returned HTTP error 400 with ContextId MS-CV=Z1ijRWzo8E2AeGB...'

 

How can I find what is wrong with my request?

@Sayali-MSFT  - thanks I figured it out. There was a syntax error -- likely in how I sent my attachment, but I can't remember exactly where it occurred.
