我在我的项目中将Ruby版本从2.7.3升级到3.2.0，一些测试开始失败，其中一个测试使用关键字参数调用函数，它抛出的错误如下：

1) NotificationsMailer notify Sets body
 Failure/Error:
   def notify(recipient_emails:, subject:, body:)
     @body = body
     @subject = subject
     mail(bcc: recipient_emails, subject: @subject, reply_to: VENDOR_SUPPORT_EMAIL)
   end

 ArgumentError:
   wrong number of arguments (given 1, expected 0; required keywords: recipient_emails, subject, body)
 # ./app/mailers/notifications_mailer.rb:5:in `notify'
 # /usr/local/bundle/gems/actiontext-6.1.6/lib/action_text/rendering.rb:20:in `with_renderer'
 # /usr/local/bundle/gems/actiontext-6.1.6/lib/action_text/engine.rb:59:in `block (4 levels) in <class:Engine>'
 # ./spec/mailers/notifications_mailer_spec.rb:16:in `block (3 levels) in <top (required)>'

下面是被调用函数的定义：

class NotificationsMailer < ApplicationMailer

  VENDOR_SUPPORT_EMAIL = "vendor-support@saatvamattress.com"

  def notify(recipient_emails:, subject:, body:)
    @body = body
    @subject = subject
    mail(bcc: recipient_emails, subject: @subject, reply_to: VENDOR_SUPPORT_EMAIL)
  end

end

这是测试文件：

require "rails_helper"

RSpec.describe NotificationsMailer, type: :mailer do
  describe 'notify' do
    let(:recipient_emails) { %w[test@mail.com test2@mail.com] }

    let(:mail) do
      NotificationsMailer.notify(
        recipient_emails: recipient_emails,
        subject: 'subject',
        body: 'body'
      )
    end

    it 'Sets body' do
      expect(mail.body.encoded).to match 'body'
    end

    it 'Sets subject' do
      expect(mail.subject).to eq 'subject'
    end

    it "Does not set To" do
      expect(mail.to).to be_nil
    end

    it "Does not set CC" do
      expect(mail.cc).to be_nil
    end

    it "Sets BCC with recipients' emails" do
      expect(mail.bcc).to eq ['test@mail.com', 'test2@mail.com']
    end

    it 'Sets reply_to with vendor support email' do
      expect(mail.reply_to).to eq ['vendor-support@saatvamattress.com']
    end
  end
end

我知道ruby 3对关键字参数做了一些修改，但是当我用相同的顺序调用函数并指定所有的关键字时，我看不出问题出在哪里。
在一些线程之后，我尝试以散列形式发送参数和其他一些不太有希望的东西，但仍然得到错误，不知道那里发生了什么。
