Null error in SQL Statement

[lamngue]

class Product(db.model):
    __searchable__ = ['title', 'description']

    __analyzer__ = StemmingAnalyzer()
    __tablename__ = "Product"
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    description = db.Column(db.Text, nullable=True)

 query = request.args.get('q', '') -> Organization
 products = Product.query.search(query, limit=num_posts)

@datapilot.before_first_request
def bootstrap():
    flask_whooshalchemy3.search_index(datapilot, Product)

The query variable is being passed but the SQL query is built into SELECT * From Product WHERE null
