Invalid date and time; Ruby on the rails

I am running a test with postings in Ruby on Rails and I am getting the following errors:

*********-C02MGBVJFD57:myapp ************$ bundle exec rake test:mailers

# Running:

When I check the users.yml file of my inventory, I see that I am using the ruby ​​timezone marker:

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>
  admin: true
  activated: true
  activated_at: <%= Time.zone.now %>

archer:
  name: Sterling Archer
  email: duchess@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

lana:
  name: Lana Kane
  email: hands@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

mallory:
  name: Mallory Archer
  email: boss@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

<% 30.times do |n| %>
user_<%= n %>:
  name:  <%= "User #{n}" %>
  email: <%= "user-#{n}@example.com" %>
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>
<% end %>  

      

        
        
        
      

    

and my db / seeds.rb file looks like this:

User.create!(name:  "Example User",
             email: "example@railstutorial.org",
             password:              "foobar",
             password_confirmation: "foobar",
             admin: true,
             activated: true,
             activated_at: Time.zone.now)

99.times do |n|
  name  = Faker::Name.name
  email = "example-#{n+1}@railstutorial.org"
  password = "password"
  User.create!(name:  name,
               email: email,
               password:              password,
               password_confirmation: password,
               activated: true,
               activated_at: Time.zone.now)
end

      

        
        
        
      

    

EDIT: Here are the tests

test / senders / user_mailer_test.rb:

require 'test_helper'

class UserMailerTest < ActionMailer::TestCase

  test "account_activation" do
    mail = UserMailer.account_activation
    assert_equal "Account activation", mail.subject
    assert_equal ["to@example.org"], mail.to
    assert_equal ["from@example.com"], mail.from
    assert_match "Hi", mail.body.encoded
  end

  test "password_reset" do
    mail = UserMailer.password_reset
    assert_equal "Password reset", mail.subject
    assert_equal ["to@example.org"], mail.to
    assert_equal ["from@example.com"], mail.from
    assert_match "Hi", mail.body.encoded
  end
end

      

        
        
        
      

    

Is there something I am doing wrong? Thanks for the help.
