i get an error when calling a webservice, i get the following error message

System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: Fault occurred while processing. faultcode=soap:Server faultactor=

I could not find the entire error message due to a salesforce limitation, here is the code that cause the error:

              new String[]{endpoint_x,

do you have an idea why i am getting this error Or how to trace the entire error message ?

    You should post the response the service is sending. You should be able to get your callout from your debug logs and put that into postman or a similar app to see what the server response is. Feb 3, 2017 at 15:15

  • In your debug log there should be a line starting with CALLOUT_REQUEST that has the callout string. Feb 3, 2017 at 16:26
  • Also you have your CALLOUT_RESPONSE just below it that will have the error in it. But I prefer to put the initial request into postman so I can tweak the body until I have fixed what is causing the error. Feb 3, 2017 at 16:47

This is probably not the answer to the OP's problem, but gives a run down of how to go about trouble shooting the issue.

How to troubleshoot your problem

  • First grab the request from your debug logs.

Should be noted here that the CALLOUT_RESPONSE is just below the request. That will have your particular error. I just prefer to put it into Postman for readability as well as being able to alter the request "on the fly" to help solve the problem with the request.

  • Put that into Postman or equivalent app

  • See the response error

In this particular issue I had to track back to the original wsdl and found out that the Type is an enumeration. Which a '' is not a valid value for. This probably won't be your particular issue. But I think this should get you going on how to find your issue.
