Swift Cannot read properties of undefined (reading 'passwordless_method') while trying to login using email and password

Hello everyone,

I have been facing an issue while implementing Auth0 with a username and password authentication method. Every time I try to log in, the login fails, and I receive the following error message: “Cannot read properties of undefined (reading ‘passwordless_method’)”. Additionally, the status code returned is 500.

Here is the code snippet I am using for the login process:

        usernameOrEmail: "pratik@engrossinfotech.com",
        password: "xxx@12345",
        realmOrConnection: "Username-Password-Authentication",
        audience: "https://example.us.auth0.com/api/v2/",
        scope: "openid profile email offline_access"
    .start { result in
        switch result {
        case .failure(let error):
        case .success(let credentials):

– Version: Release 2.3.2 · auth0/Auth0.swift · GitHub
– Mac M2 and M1
– I have also tested the login functionality using WebAuth, and it worked without any issues.
– I have also allowed the Password in the Grant Types.

Any guidance or suggestions on resolving this issue would be greatly appreciated.

Thank you.
