fix invalid type for callback #185

Closed doekenorg closed 7 months ago

doekenorg commented 11 months ago

In a previous attempt to fill out a forms columns, I've added a null value to add an empty cell. The callback expected a BaseValue.

This PR fixes that, and makes sure it is a valid empty string object.
