When passing malformed GeoJSON, either using incorrect GeoJSON values or
simply malformed JSON, a GDALException is raised:

https://github.com/django/django/blob/stable/4.2.x/django/contrib/gis/gdal/prototypes/errcheck.py#L75

This differs from the GEOSException that is thrown when passing in WKT:

https://github.com/django/django/blob/stable/4.2.x/django/contrib/gis/geos/prototypes/errcheck.py#L32

The GEOSException is handled during form deserialization, but not the
GDALException, during widget deserialization:
https://github.com/django/django/blob/stable/4.2.x/django/contrib/gis/forms/widgets.py#L54

This seems to be handled properly during field deserialization:
https://github.com/django/django/blob/stable/4.2.x/django/contrib/gis/forms/fields.py#L46

This remains an issue with the 5.2.x. branch.
