Message "line -1: Response is missing or empty" when submitting a POST message

Hey Ron,

Right I did a quick comparison and I can see the differences between the 2 payloads (no namespace references on each of the elements, in the customerNo element in soapui payload there is an erroneous ? character and 
the xmlns:shop namespace reference attribute is moved from the Envelope element to an attribute of the PurchaseSingleItem element) and I think we need to look elsewhere.   It doesnt help that it appears youre using anon authorization cos this at least indicates if the endpoint gets hit or not.

Normally I compare the RAW of each request to determine what's missing, but with this issue that's exactly the problem - there are some UI config changes that could possibly sort this - please see the following stackoverflow post and make appropriate changes. 

Does that fix it?

If not, we need to run the requests using Fiddler so we can see the differences between the requests.  Fiddler captures the HTTP/HTTPS traffic and allows you to compare - you could use the SoapUI and HTTP logs - but I find them a little confusing in SoapUI and Fiddler presents them better for comparison.

So -

1. download Fiddler (it's freeware)

2. setup Fiddler to proxy your Wizdler traffic

3. Submit Wizdler request 

4. Capture the RAW request and response details and paste into notepad for later comparison

5. setup Fiddler to proxy your SoapUI traffic

6. configure proxy settings in SoapUI

7. Enable the proxy

8. Submit SoapUI request

9. Capture the RAW request and response details and paste into notepad for comparison against Wizdler

10. Compare the request of Wizdler (successful) against the SoapUI request - this should indicate what's missing/wrong in the SoapUI request if the 'fix' isn't UI config.

Cheers,

Rich
