SOAP Fault: NullReferenceException

Question

I am trying to connect to a webservice using Classic ASP. I am using the method FindCompanies... but its giving following error, confused on how to sort it please help

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Server</faultcode>
            <faultstring>System.Web.Services.Protocols.SoapException: Server was unable to process request. ---&gt; System.NullReferenceException: Object reference not set to an instance of an object.
               at App.Apis.v_1_5.CompanyApi.FindCompanies(ApiCredentials credentials, String conditions, String orderBy, Nullable`1 limit, Nullable`1 skip)
               --- End of inner exception stack trace ---
            </faultstring>
            <detail />
        </soap:Fault>
    </soap:Body>   
</soap:Envelope>

My ASP code is below

<%
msURL = "https://myconnectwise.net/v4_6_release/apis/1.5/CompanyApi.asmx"

'set up xmlhttp to checkout server
Dim oRequest
Set oRequest = Server.CreateObject("MSXML2.ServerXMLHTTP")

'setting this option will allow ServerXMLHTTP to ignore the certificate errors it encounters.
oRequest.setOption(2) = SXH_SERVER_CERT_IGNORE_ALL_SERVER_ERRORS



' resolve, connect, send, receive - in milliseconds
oRequest.setTimeouts 10000, 10000, 10000, 10000

msSOAP = "<?xml version=""1.0"" encoding=""utf-8"" ?>"
msSOAP = msSOAP & "<s:Envelope xmlns:s=""http://schemas.xmlsoap.org/soap/envelope/"">"
msSOAP = msSOAP & "<s:Body>"
msSOAP = msSOAP & "<FindCompanies xmlns=""http://connectwise.com/FindCompanies"">"
msSOAP = msSOAP & "<CompanyName>training</CompanyName>"
msSOAP = msSOAP & "<IntegrationLoginId>xxx</IntegrationLoginId>"
msSOAP = msSOAP & "<IntegratorPassword>xxx</IntegratorPassword>"
msSOAP = msSOAP & "<Conditions>CompanyName like ""Connect*"" and City = ""new jersey""</Conditions>"
msSOAP = msSOAP & "  <orderBy>string</orderBy>"
msSOAP = msSOAP & "      <limit>int</limit>"
msSOAP = msSOAP & "      <skip>int</skip>"
msSOAP = msSOAP & "</FindCompanies>"
msSOAP = msSOAP & "</s:Body>"
msSOAP = msSOAP & "</s:Envelope>"

oRequest.Open "POST", msURL, False
oRequest.setRequestHeader "Content-Type", "text/xml"
oRequest.setRequestHeader "SOAPAction", "http://connectwise.com/FindCompanies"
oRequest.send msSOAP

Response.Write oRequest.responseText
%>

According to your given asmx link the wsdl prints out a demo request (just open in browser!)

So I think your request misses some parameters/has some wrong tags/structure! Sending in this generated demo request

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:con="http://connectwise.com">
  <soapenv:Header/>
  <soapenv:Body>
    <con:FindCompanies>
      <!--Optional:-->
      <con:credentials>
        <!--Optional:-->
        <con:CompanyId>asdf</con:CompanyId>
        <con:ContactId>123</con:ContactId>
        <!--Optional:-->
        <con:IntegratorLoginId>asdf</con:IntegratorLoginId>
        <!--Optional:-->
        <con:IntegratorPassword>asdf</con:IntegratorPassword>
        <con:PortalConfigId>123</con:PortalConfigId>
        <!--Optional:-->
        <con:MachineId>asdf</con:MachineId>
      </con:credentials>
      <!--Optional:-->
      <con:conditions>asdf</con:conditions>
      <!--Optional:-->
      <con:orderBy>asdf</con:orderBy>
      <con:limit>123</con:limit>
      <con:skip>123</con:skip>
    </con:FindCompanies>
  </soapenv:Body>
</soapenv:Envelope>

did give me a result!

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Client</faultcode>
         <faultstring>Cannot find company in connectwise config.xml: asdf</faultstring>
         <faultactor>PSA</faultactor>
         <detail>
            <text>Cannot find company in connectwise config.xml: asdf</text>
            <type>CompanyNotFoundError</type>
         </detail>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

I have run into this issue as well. It seems the value provided in <CompanyName>training</CompanyName> is not the same company name/id you use when logging into Connectwise. If it is the same make sure it is the one you logged in with when you created the Integrator Login as I believe they get tied together at that point.

As a guess I'd say part of the problem is the OrderBy, limit and skip fields don't appear to have correct values. i.e.

OrderBy should be the name of a column
limit should be a number
skip should be a number

(This is of course just a guess, I don't know how the API works!)

The error is basically saying that the service can't find a variable or it hasn't been initialised correctly (Object reference not set to instance of an object).

Read the fault message. It is clearly an exception in the service. The service has thrown a NullReferenceException.

If this is due to the parameters you are passing, then it is still a bug in the service - the parameters should have been checked before the service operation began.
