Cannot send emails through SMTP

Hey guys, just deployed Accent into a kubernetes cluster using canonical mirego/accent:v1.16.3 docker image, trying to invite people into a test project to check everything, but it throws error:

06:54:12.244 [warning] Expected Elixir.Accent.Hook.Outbounds.Email.perform/1 to return:

- `:ok`
- `:discard`
- `{:ok, value}`
- `{:error, reason}`,
- `{:cancel, reason}`
- `{:discard, reason}`
- `{:snooze, seconds}`

Instead received:

%Bamboo.Email{
  from: {"Accent", "%REDACTED%"},
  to: [nil: "%REDACTED%"],
  cc: [],
  bcc: [],
  subject: "Accent – Invitation to collaborate on \"test\"",
  %EMAIL_BODY_REDACTED%
  private: %{
    html_layout: {Accent.EmailLayoutView, "index.html"},
    text_layout: {Accent.EmailLayoutView, "index.text"},
    view_module: Accent.EmailView,
    view_template: :project_invite
  }
}

The job will be considered a success.

seems like bamboo_smtp should be updated, since 2.1.0 is 4 years old and the latest release is 4.2.2
