Assume that you use Microsoft SQL Server Reporting Services to create a report that contains a date type parameter. When you execute the report by using an invalid date parameter, you receive the following error message:
The value provided for the report parameter parameter_name is not valid for its type. (rsReportParameterTypeMismatch)
This is the expected behavior. However occasionally, you may also receive the following error message:
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
If you replace the invalid date parameter with the correct date and then execute the report, you still receive the same error message. This issue is not resolved until you refresh the current webpage.
