Plone6 add object error

Have been getting this error, please help.

Using these versions: Python = 3.9.13 Plone = 6.0.0a4 collective.z3cform.datagridfield = 3.0.0.dev0 (master branch) z3c.form = 4.3 plone.autoform = 2.0.0a1 plone.z3cform = 2.0.0a2 plone.app.z3cform = 4.0.0a9

This is my content type:

class IPersonRowSchema(interface.Interface):
    Fullname = schema.TextLine(title=u"Fullname")
    Email = schema.TextLine(title=u"Email")

class IContact(model.Schema):
    """ Marker interface and Dexterity Python Schema for Contact
    """
    directives.widget(Person='collective.z3cform.datagridfield.datagridfield.DataGridFieldWidgetFactory')
    Person = schema.List(
        title=_(u'label_person', default=u'Person'),
        description=_(u'help_person', default=u''),
        required=False,
        value_type=DictRow(
            title=u"personrow",
            schema=IPersonRowSchema,
        ),
    )
