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

Describe the ideal solution

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:

Auth0
.authentication()
.login(
usernameOrEmail: "xxx@engrossinfotech.com",
password: "xxx@12345",
realmOrConnection: "Username-Password-XXXXXXXX",
audience: "https://company.com/api/v2/",
scope: "openid profile email offline_access"
)
.start { result in
switch result {
case .failure(let error):
print(error.localizedDescription)
case .success(let credentials):
print(credentials)
}
}

Alternatives and current workarounds

No response

Additional context

Note:

• Version: Release 2.3.2
• 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.

Hello everyone,

I have identified the issue, and it is not related to the library. I am sharing the details here so that it can help anyone who may encounter a similar problem.

The web developers have implemented a rule that applies to all applications. Within that rule, there is a condition that checks if the passwordless_method parameter in the request has a value of 'SMS'. However, in the request I was sending from the mobile device, the parameter was not passwordless_method. As a result, the rule encountered an error, leading to the issues mentioned earlier.
