Payload validation error: ‘Object didn’t pass validation for format absolute-https-uri-or-empty: http://127.0.0.1:3000/login’ on property initiate_login_uri (Initiate login uri, must be https).
The login_url should point to a route in the application that ends up redirecting to Auth0’s /authorize endpoint, e.g. https://mycompany.org/login . Note that it requires https and it cannot point to localhost .
If you can provide more details about your use-case for an application URI I might be able to assist further, also I want to double check and make sure you’re not referring to a callback URL which does allow the use of localhost.
