This is my sqlalchmey model, but it throws the below exception.

from sqlalchemy.dialects.postgresql import  UUID

class Test(Base):
    __tablename__ = "test"

    id = Column(
        UUID,
        server_default=sqlalchemy.text("uuid_generate_v4()"),
        primary_key=True,
        info={'form_field_class': TextField}, # <-- This should have been rendered as textfiled ?
    )

Form:

        class ObjectForm(ModelForm):
            class Meta:
                model = Test

exception:
wtforms_alchemy.exc.UnknownTypeException: Unknown type 'UUID()' for column 'organization_id'
This is a very common data type used while using postgres backend in sqlalchemy.
