Maybe it’s bad practice, but in my flow I use Script connectors to create data which I pass through the flow in Message Headers.
Sometimes, it’s useful to download the message, adjust it and re-upload it.
However this only works for the XML body of a message. Headers can’t be downloaded and re-uploaded.
It would be useful if we could download the full message with headers, in a format which could be edited (XML) and be able to re-upload it into the connector
