openapi: web unaccessible when authentication enabled on nginx

[mkrnac-implemento]

When authentication is enabled on nginx, odoo web (backend) is unaccessible at all.
It is enabled on nginx like this:

    auth_basic "Protected area";
	auth_basic_user_file /etc/nginx/.htpasswd;

and here is the stack:

This is our test instance, which is not supposed to be accessed by public, that is the reason why we need authentication enabled on nginx. REST API should be accessed directly bypassing nginx web server (through ssh tunnel).

Hello!
This seems doesn't related to openapi module directly. For example, the logs even has error about /longpolling/poll

Nov 22 03:46:09 odoo-test odoo[127094]: werkzeug.exceptions.BadRequest: 400 Bad Request: <function BusController.poll at 0x7f5732afc5e0>, /longpolling/poll: Function declared as capable of handling request of type 'json' but called with a request of type 'apijson'
