I have a Microsoft Flow which pulls a SharePoint List item and it's attachments, creates a message, then sends that message to Teams through a Webhook connector.
In order to send the attachments, I am required to send the
Base64 representation. I believe this is making the message too large, as I am receiving
HTTP 413 response.
The message I am sending is correct (I tested it in the Actionable Message playground), but it's the connection (HTTP POST to Teams) which is failing. Please help me understand what I can do to allow the large message to pass through.
The HTTP Post returns
200, but the body says:
Webhook message delivery failed with error: Microsoft Teams endpoint returned
HTTP error 413with
