Export geometry to esri shp

I am tryong to export geometry to shape file,but there is a error:
SNAP - Export Geometry as ESRI Shapefile

Can not export geometry.

java.io.lOException: Could not find attribute crop_ Polygon (mul count: 0
but there are some geometrys.
so how can i solve the problem?

A work around is explained here: Ship Detection - cannot export Geometry as Shapefile
