Version: Odoo 14.0

How can I create a public route to access stock data without login authentication?

@http.route('/nuanju/stock_report', auth='public', website=True, methods=['GET']) For this request, I'm getting this error :

odoo.exceptions.AccessError: You are not allowed to access 'Quants' (stock.quant) records.

This operation is allowed for the following groups:

- Inventory/Administrator

- Inventory/User

- User types/Internal User

Contact your administrator to request access if necessary.

I have also one public user in database
