We configured the Application Login URI with a URL that includes ‘localhost’ ( e.g. https://localhost/3000/callback ) and received the below error.
"Error! Payload validation error: 'Object didn't pass validation for format absolute-https-uri-or-empty: https://localhost:7290/callback'; on property initiate_login_uri (Initiate login uri, must be https)."
For the field ( “Application Login URIs” ), you cannot use localhost, and it requires https://, as stated in this document:
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
login_url can include query parameters and a URI fragment.”
Therefore, please make sure that “Application Login URI” does not specify ‘localhost’.
