Internal Error when using date filter on custom reports

When I tried to make a Custom Report and by using any condition related to date and select “between” and if I instert any date range this error appears

What happens when you change the first dates ?

In the example you showed, the report select transactions dated 9/6/2020, so it probably has no transactions to use for the selection by the Payment or Receipt / Date field

the same error appears

I can reproduce this - it seems like a bug
Custom report with no Where clause (note Payment or Receipt/Date has a few records with data


Add a where clause

give Internal error

Thanks. Fixed in the latest version (20.6.80)

Sorted - at least for my custom report
