[Qgis-user] Problems to export as a GeoPackage

[José Carlos Guerrero Antúnez]

Hi,

I am having trouble saving a shapefile as geopackage.

The error message is this,
Export to vector file failed.

Error: Feature write errors:

Feature creation error (OGR error: failed to execute insert : UNIQUE
constraint failed: sa_area_estudio.fid)


I'm working in MacOS (Mojave) and QGIS LTR 3.10.


Many thanks in advance,
