SSRS report Execution Errors

Hello Friends,

I have report builder 3.0 with SQL 2012.

When I try to run report on my report builder, receiving below errors.

System.Web.Services.Protocols.SoapException: An unexpected error occurred in Report Processing. ---> System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at Microsoft.ReportingServices.Library.ReportingService2010Impl.CreateReportEditSession(String Report, String Parent, Byte[] Definition, String& EditSessionID, Warning[]& Warnings)
   at Microsoft.ReportingServices.WebServer.ReportingService2010.CreateReportEditSession(String Report, String Parent, Byte[] Definition, String& EditSessionID, Warning[]& Warnings)

Please help.

Thanks.
