ArgumentError: SMTP From address may not be blank

[kaka-ruto]

I am getting the above exception after successfully subscribing a user to a monthly plan, in development. This is my mailer and I am clearly passing the from address

class PlanSubscriptionMailer < ApplicationMailer
  def successful_subscription
    @user = User.find_by(email: params[:user_email])

    mail(
      from: "email@email",
      to: email_address_with_name(@user.email, @user.full_name),
      subject: "HP: Successful subscription!"
    )
  end
end

The stack trace point to the letter opener gem I am using on dev

/Users/kaka/.asdf/installs/ruby/3.2.2/lib/ruby/gems/3.2.0/gems/letter_opener-1.8.1/lib/letter_opener/delivery_method.rb:32:in `validate_mail!'

Other emails are being set well and show correctly on dev via the letter opener gem.

Do pay gem emails not work well with Letter opener? (haven't tested on production yet)

[deanpcmad]

I think the email address is set in the pay.rb initializer file as the support_email - https://github.com/pay-rails/pay/blob/main/docs/2_configuration.md#configuration

You will want to set a default from address in your ApplicationMailer, or use the mailer_arguments config in the docs that @deanpcmad mentioned.
