Is there a way to send plain XML or JSON body in POST request in HttpRetriever? Even if I add new Content-type=application/xml header, I get "Bad request" answer from the server. Alternatively, if I do not convert my XML column to BLOB, it can't be used by HttpRetriever.
I see the change in this node UI but somehow it doesn't affect final outcome - still getting Bad Request. This picture shows how I defined new content type:
It very much might be a problem with something else but there is no log to see actual HTTP requests issued by this node.
