When I was testing OLMIS-6473, I noticed that the reporting rate report is no longer generated in the XLS format. When trying to do so, the error from the screenshot occurs. The issue occurs on both browsers.
Log into the application as administrator.
Go to Reports > View Reports.
Choose the "Reporting rate report" link.
Try to generate the report in the XLS format for any program and processing period.
The report isn't generated. Instead, the error from the screenshot occurs.
It should be possible to generate the report in the XLS format.
