I have a back-end server that is making a post call to my API Gateway with a body, using the following header:
The gateway then routes it to the endpoint which is a vendor URL, but it does not make it to the Vendor at all...
What's even more intriguing is that the request message does not even get logged in the gateway. Instead I get the following message:
"Unable to get request XML: Multipart stream ended before a terminating boundary was encountered"
Not sure what is happening, but it seems that the Gateway does not like this header and is rejecting it before it can even route the message.
