'Point' object has no attribute 'geometry_type'

Hi! I’ve made a tryton model that uses tryton gis fields but it isn’t working when I try to open the costume module it sends this error message:

Traceback (most recent call last):

AttributeError: 'Point' object has no attribute 'geometry_type'

Fault: 'Point' object has no attribute 'geometry_type'

Here is my model:

from trytond.pool import Pool
from trytond_gis import fields as geo_fields
from trytond.model import ModelSQL, fields, ModelView

__all__ = ['Jardin']

class Jardin(ModelSQL, ModelView):
    "Jardin"
    __name__ = 'training.jardin'
    _rec_name = 'description'

    position = geo_fields.Geometry("Position")
    point = geo_fields.Point("Point")

My jardin table:
