I am trying to find a way to customize the export csv on my entity admin.
Ideally, I need to extract the data from the functions of my entity to put it in the csv file.
I list the fields I want to extract with the configureExportFields() function, and i tried to modify the request with the getDataSourceIterator() method but it seems to error the export.
If anyone know how to do this using the default sonata export
on PHP 8
I found this solution Sonata admin export fields with collection fields.
