Trying to use PasswordlessEmail flow doesn't work

[gabrielvillage]

Hello! I'm trying to implement Auth0 on my Unity project and when calling the StartPasswordlessEmailFlowAsync I get the following error:
Error Unity Auth0.Core.Exceptions.ApiError : {"error":"bad.connection","error_description":"Missing required property: connection"}
I don't know how to fix it as the PasswordlessEmailRequest doesn't have a Connection parameter and digging into the StartPasswordlessEmailFlowAsync method it shows it sets the connection type to "email".

Here's the code I'm using:

        var request = new PasswordlessEmailRequest()
        {
            ClientId = clientId,
            ClientSecret = authManager.Settings.ClientSecret,
            Email = emailField.text,
            Type = PasswordlessEmailRequestType.Link,
        };

        PasswordlessEmailResponse response = null;
        ErrorApiException apiError = null;

        try
        {

            response = await authManager.Auth0.StartPasswordlessEmailFlowAsync(request);
        }
        catch (ErrorApiException ex)
        {
            apiError = ex;
        }

        if (apiError != null)
        {
            Debug.LogError(apiError.ApiError + " : " + apiError.Message);
            return;
        }
        Debug.Log($"{response.Email} : {response.EmailVerified} : {response.Id}");

👋 I just tried the following using the underlying SDK, and it works fine for me:

var request = new PasswordlessEmailRequest
{
    ClientId = GetVariable("AUTH0_CLIENT_ID"),
    ClientSecret = GetVariable("AUTH0_CLIENT_SECRET"),
    Email = GetVariable("AUTH0_PASSWORDLESSDEMO_EMAIL"),
    Type = PasswordlessEmailRequestType.Link
};

var response = await authenticationApiClient.StartPasswordlessEmailFlowAsync(request);
response.Should().NotBeNull();
response.Email.Should().Be(request.Email);
response.Id.Should().NotBeNullOrEmpty();
response.EmailVerified.Should().NotBeNull();

So the underlying SDK seem to behave fine.
Can you call the endpoint using CURL, does it return the same response?

curl --request POST \
  --url 'https://{yourDomain}/passwordless/start' \
  --header 'content-type: application/json' \
  --data '{"client_id":"{yourClientId}", "client_secret":"{yourClientSecret}", "connection":"email", "email":"USER_EMAIL", "send":"link"}'

If it does, can you verify if your Auth0 tenant is configured correctly?

[gabrielvillage]

Thanks for the response. The CURL call does work. What should be the correct Auth0 tenant setup?

[frederikprijck]

If the curl works, the tenant is set up correctly. I will look into something else and get back to you. Im wondering if the version of auth0.net, used in the unity SDK, might be related.

[frederikprijck]

I can't seem to reproduce this using Auth0.NET 7.15.0 neither, which should be the version used by the Unity SDK.

Any chance you can test it using straight up Auth0.NET yourself to help identify where the origin of the issue could be?

Come on guys you have the opportunity to be the sole auth provider for Unity VR and you abandon this?
