I have designed a workflow which after form submission is supposed to assign permissions to a approver using the "Call Web service" action item. This action item completes at almost all times, but sometimes it runs into an error with the following error message-
"Failed to invoke web service. Error returned from server: <soap:Fault xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>soap:Server</faultcode><faultstring>Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was th..."
This is an intermittent issue and hence cannot be replicated at all times.
Can anyone give me reason why this error shows up sometimes when using the "Call Web service" action.
