Apigee returns 503, "service temporarily unavailable", for SOAP request

[sanketjahagirda]

I have soap UI project, WS-Security settings are as attached. SOAP UI is generating security header and WSSE validation is done by the backend.

I have created passthrough reverse proxy and trying to invoke backend with soap request. I see error in my backend logs as Security header not present in the request received.

In Apigee trace logs,I get the error 503, service temporarily unavailable. Now I am trying to find out where is my lost header. Can anyone help me with it?

Who's throwing 503, your backend or Apigee?

In the trace tool, can you see all the headers arriving to Apigee?

Apigee was throwing error to the client. In the trace tool, I saw I received soap request with security headers already. In fact, it wasnt even reaching to the backend and I was checking non relevant logs.

I figured out the issue as https url of target backend was causing an issue. I changed it to http and it worked.

This is related to CORS, and to be able to solve it, you will need to enable CORS when creating the proxy
