System.CalloutException: Web service callout failed: Unable to find field

Wsdl2Apex Generated Class:

public class wwwTheyukicompanyCom1 {

            response_map_x.put('response_x', response_x);
            WebServiceCallout.invoke(
              this,
              request_x,
              response_map_x,
              new String[]{endpoint_x,
              'http://www.theyukicompany.com/ProcessSalesInvoices',
              'http://www.theyukicompany.com/',
              'ProcessSalesInvoices',
              'http://www.theyukicompany.com/',
              'ProcessSalesInvoicesResponse',
              'wwwTheyukicompanyCom1.ProcessSalesInvoicesResponse_element'}
            );
            response_x = response_map_x.get('response_x');
            return response_x.ProcessSalesInvoicesResult;
        }
    }
}

I am trying to call ProcessSalesInvoices() in SalesSoap class using below from anonymous window:

wwwTheyukicompanyCom1.SalesSoap s = new wwwTheyukicompanyCom1.SalesSoap();
wwwTheyukicompanyCom1.xmlDoc_element xmldoc = new wwwTheyukicompanyCom1.xmlDoc_element();
s.ProcessSalesInvoices('','',xmldoc);

Executing above gives the error: Value cannot be null for parameter "xmlDoc"

In above wsdl2apex generated class, 'xmldoc_element' class have only private variables in it. So I changed the class as below for testing:

public class xmlDoc_element {
    private String[] apex_schema_type_info = new String[]{'http://www.theyukicompany.com/','true','false'};
    private String[] field_order_type_info = new String[]{'*'};
}

running the same above code from anonymous window now gives the error: System.CalloutException: Web service callout failed: Unable to find field '*' found in fieldOrder

How can I identify and fix the exact issue?

Answer 1

The problem with xmlDoc is that it originates from this part of the WSDL.

<s:element name="ProcessSalesInvoices">
  <s:complexType>
    <s:sequence>
      <s:element minOccurs="0" maxOccurs="1" name="sessionId" type="s:string"/>
      <s:element minOccurs="0" maxOccurs="1" name="administrationId" type="s:string"/>
      <s:element minOccurs="0" maxOccurs="1" name="xmlDoc">
        <s:complexType mixed="true">
          <s:sequence>
            <s:any/>
          </s:sequence>
        </s:complexType>
      </s:element>
    </s:sequence>
  </s:complexType>
</s:element>

Basically, it is using <xsd:any> (from http://www.w3.org/2001/XMLSchema).

WebServiceCallout.invoke doesn't support this, so you need to work around it.

The Salesforce datatype anyType is not supported in WSDLs used to generate Apex code that is saved using API version 15.0 and later. For code saved using API version 14.0 and earlier, anyType is mapped to String. Source

When I encounter <xsd:any> I'll convert it to either a string or List<DOM.XmlNode>. It isn't perfect, but will at least give you something to start from.

Another way to work around it is to generate the raw HTTP request and parse the response.

E.g. Where you would use wwwTheyukicompanyCom.SalesSoap.ProcessSalesInvoices_Http()
