I am on phoenix version 1.8.0-rc.4. I have added Ash authentication using mix igniter task.

When I run the code and try to register a user. I get:

1. Message in UI - “If this user exists in our database, you will be contacted with a sign-in link shortly.”
2. A warning in server log - [warning] Error sending magic link email
3. And the dev mailbox (http://localhost:4000/dev/mailbox) is empty.

I checked that this function does not get called - Helpdesk.Accounts.User.Senders.SendMagicLinkEmail.send. So, error must be happening before this.

Here is the server log

[debug] HANDLE EVENT "submit" in AshAuthentication.Phoenix.SignInLive
  Component: AshAuthentication.Phoenix.Components.MagicLink
  Parameters: %{"_csrf_token" => "ZVgaESoEJG59ASRhNycCBTYHTWURUkJcW3kCNobVJhsW_cGZzWtUYg36", "user" => %{"email" => "a@example.com"}}
[warning] Error sending magic link email

%{}
[debug] Replied in 10ms

Do you know what I need to get this working. I am following documentation, but no luck so far.

Also, can you give me hints about how to dig into the code producing such errors?

Thank you.
