Forms module export response empty csv #2891

ABP Commercial 5.2.0 stable MVC, EF SQL New MVC project

When I Download the csv file exporting responses of a Forms, the csv file is **empty **even if I have several responses shown in the web interface.

The csv is requested to the api:

Am I missing something to allow answers to be in the CSV?
