We are using paid SaaS standard license. When I try to hit Backend service, I am getting below error
{ "fault": { "faultstring": "Duplicate Header \"Expires\"", "detail": { "errorcode": "protocol.http.DuplicateHeader" } } }
I checked the headers from trace and I don't see Expires header is added. I also tried adding AssignMessage policy to remove Expires header explicitly. That also didn't help. Please suggest
