I have created an API for creating a ticket. I just started working on it.

I am getting an error. When I access the API I select the related database and in that database, if my module is installed then I get the response. 
But If I open the URL in incognito mode of the browser then It gives me the error. because the database is not selected by default in incognito mode

Here is the code of the controller file

from odoo import http
from odoo.http import request
import json


class MetaWithHelpdesk(http.Controller):

    @http.route('/api/create_ticket', type='http', auth='public', methods=['POST', 'GET'], csrf=False)
    def create_ticket(self, **kw):
        print('reached')
        try:
            return json.dumps({'message': 'Ticket created successfully'})
        except Exception as e:
            return json.dumps({'error': str(e)})

here is the code of __manifest__.py
