IG&L Change Request creation through Web Service call from ServiceNow

We are working on integrating ServiceNow with IG&L for access request using the createChangeRequest web service call. Login Web Service successfully returns token to ServiceNow but when serviceNow calls createChangeRequest API, it is getting Invalid XML content in the request body. Premature end of file message though the XML payload is is passed correctly. I'm not able to figure out why it is happening.

I want to know if anyone have worked on this type of integration and faced similar issue. Any help with this would be highly appreciated.

Thanks

Shesh

I suggest you add an example of the XML you are sending.
Are you able to raise a change request via web service using a tool like postman (or curl or any any other tool)?

  Here is the sample XML for createChangeRequest service call and I can create change request in IG&L with this using SOAPUI successfully.

            <Description>Test Change Request</Description>

            <Parameters>
              <Parameter scope="public">

                <Value>CH123456</Value>
              </Parameter>
            </Parameters>

    What errors you see in the G&L log (aveksaServer.log)?

      Invalid XML content in the request body. Premature end of file
      
      This is the error I see in aveksaServer.log file and it indicates that ServiceNow is not sending XML payload while making a call to createChangeRequest service API.
      BTW, is there is a way I can change in IG&L logging settings to log the webservice call and XML payload. This way I can identify if the data was sent to IG&L or not when the web service is called.
      
      Does IG&L WebService supports JSON objects, I can only see it has support for XML.

        Try to enable debug (Admin-> System -> Logs -> Settings) for RESTWebServiceNode and RestClient
        com.aveksa.server.workflow.scripts.nodes.RESTWebServiceNode
        com.aveksa.server.workflow.webservices.rest.client.RestClient
        
        If your are on 7.1, you might not see the mentioned classes in the dropdown

        We are on 7.0.2 and I think whatever you had mentioned will be useful for REST Web Service workflow node rather than for the WebServices that are supported by IG&L. Please correct me if I'm wrong.
