I have a controller method with these details:

@http.route('/my_route/', type='http', auth='public', website=True)

def handler(self, uid_reference, **kwargs):

....

I'm trying this, but I always get 404.

http://localhost:8069/my_route/01592-051-0001

I assume it's because I'm not correctly including the name of the database I need to connect to. I tried this variant, but the result was the same

http://localhost:8069/my_path/01592-051-0001?db=my_db_name

However, if I had authenticated previously and then closed that session, there would be no problems.

What is wrong here.

Thanks in advance
