Invoke web service: Invocation Error - ALC-DSC-003-000 - Error: content is not allowed in prolog

Avatar

Level 1

I'm attempting to call a web service with the Invoke Web Service activity in livecycle ES4 and it gives me an Invocation Error.

Here is the thing.

I've tried using a direct copy paste of a soap request from SOAPUI where it works perfectly fine. More than that, I've tried using that same copy paste in the test part of the Invoke Web Service activity within livecycle where it also works perfectly fine.

When I try to invoke the process, however, it fails.

Any ideas on how to solve it?

Here is the error log:

ALC-DSC-003-000: com.adobe.idp.dsc.DSCInvocationException: Invocation error.

I dug around a bit in wireshark and found the service response which was telling me the Content-Type being text/htmlwas invalid.

I'm not sure why the livecycle soap call would register as something other than soap xml, but adding: <?xml version="1.0"?> to the beginning of our SOAP call solved the problem.
