Error on export on shapefile with geofile writer

Hi,

I’m trying to export to a shapefile with geofile writer and I have this message : “ERROR GeoFile Writer 3:8 Execute failed: field type is not supported string (field index: 0)”.

It doesn’t function with shp and geojson but it functions with geoparquet.

Is there someone with the same experience who resolved the problem ?

Thanks a lot,

Best regards,

Matthieu
