Report Server Issue Object reference not set to an instance of an object

Hi all,

I'm getting this problem 'Object reference not set to an instance of an object.' whenever I try to review a report and I checked the log file and this is what it had

w3wp!ui!1!11/14/2006-10:54:20:: Unhandled exception: System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.Reporting.WebForms.WebRequestHelper.GetExceptionForMoreInformationNode(XmlNode moreInfo, XmlNamespaceManager namespaces)
at Microsoft.Reporting.WebForms.WebRequestHelper.ExceptionFromWebResponse(Exception e)
at Microsoft.Reporting.WebForms.ServerReport.ServerUrlRequest(Boolean isAbortable, String url, Stream outputStream, String& mimeType, String& fileNameExtension)
at Microsoft.Reporting.WebForms.ServerReport.GetStyleSheet(String styleSheetName)
at Microsoft.Reporting.WebForms.ReportServerStyleSheetOperation.PerformOperation(NameValueCollection urlQuery, HttpResponse response)

at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Some previous forums stated checking the webconfig file but the web config file look okay. Is there another way to fix this.

Much Thanks,

Carl

All,

I forgot to mention that I can view the report okay in my local SQL development - When I deploy my reports to the Report Server I can not view the same reports in the Report Manager.

I get the ''Object reference not set to an instance of an object' where my report should be - Also I get this recorded in the log file:

Hi Carl,

Did you ever solve this issue? I'm getting the same error.

Thanks,
