I have a simple report attached for faster reference, my backend is SQL2K14.
I'm encountering the error below whenever I try to preview the report.

And when I remove the parameter from datasource1 shown below, the report works.

I run this exact same report in SS Designer ver 2019.2.3 and the report works without having to remove the parameter.
Is this a bug? Or is there a new way to do this in the latest SS Designer version?
Thanks,
