Upon submission form is not validated - flask

Question

I am trying to implement a form that collects data on a concert venue and stores it on my local postgres database using wtforms and flask-sqlalchemy orm.
I have noticed that my form fails to validate preventing me from adding the new record to my database. Please see the relevant code below
Form model
class VenueForm(FlaskForm):
name = StringField(
'name', validators=[DataRequired()]
)
