Answer 1

I got this error on a report I copied from another project and changed the data source. I solved it by opening the properties of my dataset, going to the Parameters section, and literally just reselecting all the parameters in the right column, like I just clicked the dropdown and selected the same column. Then I hit preview, and it worked!
