'Value cannot be null. Parameter name : s' erro while running ssrs report using reportviewer ASP.NET application

Dear All,

While running ssrs report from asp.net application using reportviewer I am getting error as 'Value cannot be null. Parameter name : s'. Also I have tried with ssrs report which doesn't contain any parameter. Still I am getting that error.

So, please help me to resolve this issue.

Thanks in advance
