500 Error? Why does the 8.5+ schema not provide the proper error statements

[patrick.murphy]

I am upgrading my tools to 8.5+ and whenever I send any requests where I generally get an error, like duplicate DN's. Instead of getting any error messages back I just get 500 errors and the debugs don't tell me anything?

This is the last thing I get, so the system never send me the exact error?

Which CUCM version are you running this request with? I tried a request with CUCM version 10.5 and AXL API 8.5, and I get an error description like this :

<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><soapenv:Fault><faultcode>soapenv:Client</faultcode><faultstring>Cannot insert or update pattern. A DN exists with the same pattern and partition.</faultstring><detail><axlError><axlcode>4052</axlcode><axlmessage>Cannot insert or update pattern. A DN exists with the same pattern and partition.</axlmessage><request>addLine</request></axlError></detail></soapenv:Fault></soapenv:Body></soapenv:Envelope>

Following up on this - are you seeing this error with some specific requests? Is this issue intermittent or reproducible? Are there large/rapid AXL requests being sent around the time the issue is seen?

[patrick.murphy]

Still not seeing much difference in my app but I am working through it. It seems that some of the error message just give me 500 Internal Server errors with very little details.

System.Net.WebException was caught

  HResult=-2146233079

  Message=The remote server returned an error: (500) Internal Server Error.

  Source=System

  StackTrace:

       at System.Net.HttpWebRequest.GetResponse()

       at WindowsApplication1.Form4.WriteSystemPartitionRoutine(String& SoapArg1, String& PartName) in C:\Visual Studio\Projects\Tool85\Tool\Form4.vb:line 2535

  InnerException:

I have looked at the details but it seems that the response does not provide me with the error message.

I found my issue in .Net. It turns out that when a WebException occurs I have to read the response from the exception and not from the initial response.

          ' Pre-version 8 the error message was captured here

           response = DirectCast(request.GetResponse(), HttpWebResponse)

           reader = New StreamReader(response.GetResponseStream())

           responseTxt = reader.ReadToEnd()

        Catch ex As WebException

           'After version 8 the error message the error message must be captured here

          response = ex.Response

          reader = New StreamReader(response.GetResponseStream())

          responseTxt = reader.ReadToEnd()

            Exit Sub
