I removed the custom converters for BigInt and updated this class we discussed in slack/email with :

class Cabinet(SQLAlchemyObjectType, CabinetAttribute):
    """Cabinet node."""

    class Meta:
        """Define the metadata."""

        model = CabinetModel
        interfaces = (graphene.relay.Node,)

    id_ = ORMField(type_=graphene.BigInt)

Here are the errors:
