I'm working on a migration of a module that was developed for Odoo 11 and I want to use in Odoo 15, I try to use the plugin odoo-module-migrator, which I can install but, when I access the website section that is included in this module I receive the following error:

Traceback (most recent call last):

Exception
The above exception was the direct cause of the following exception:

AttributeError: 'ir.model.data' object has no attribute 'get_object'

and this is the code that builds this website section:

@http.route('/directory', type="http", auth="public", website=True)    
def directory_search(self, **kwargs):
        featured_listings = request.env['res.partner'].sudo().search([('in_directory','=', True), ('featured_listing','=',True) ])
        regular_listings = request.env['res.partner'].sudo().search([('in_directory','=', True), ('featured_listing','=',False) ])
        google_maps_api_key = request.env['ir.config_parameter'].sudo().get_param('google_maps_api_key')
        directory_categories = request.env['res.partner.directory.category'].sudo().search([('parent_category','=',False)])
        page_directory_search = request.env['ir.model.data'].get_object('website_business_directory', 'page_directory_search')
        return http.request.render(page_directory_search.view_id.id, {'featured_listings': featured_listings, 'regular_listings': regular_listings, 'google_maps_api_key': google_maps_api_key, 'directory_categories': directory_categories} )
