My purpose is to query the context on Orion broker with a node-red flow.
In a Node-RED function node I set my json format query on the msg.payload property.
On headers When I set 'Content-Type':'application/json' header I get an error:
"Orion accepts no payload for GET/DELETE requests. HTTP header Content-Type is thus forbidden"
So I remove this header but then I get a reply about
"JSON parse error"
and
connection: "close" content-length: "0" allow: "POST".
My json query on payload is valid as validator says.
