The report execution <ID> has expired or cannot be found. (rsExecutionNotFound)
I see this error every so often and it always occurs when I “wake” my PC and re-fresh a SQL Server Reporting Services (SSRS) report.
There isn’t really a fix for this, but all you need to do is re-run the original report. This will give you a new SSRS ID and everything will be good.
