Psych::SyntaxError: (<unknown>): did not find expected key while parsing a block mapping at が解決できません

YAML syntax error occurred while parsing /app/config/database.yml. Please note that YAML must be consistently indented using spaces. Tabs are not allowed. Error:

Psych::SyntaxError: (<unknown>): did not find expected key while parsing a block mapping at line 12 column 1というエラーが出ます
tabではなくてスペースキーを使ってくださいという記事がたくさん出てきたのでそれをやってみたのですが、なかなか解決できません。

お手数ですが、コードを確認して欲しいです

database.yml

# MySQL. Versions 5.1.10 and up are supported.
#
# Install the MySQL driver
#   gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
#   gem 'mysql2'
#
# And be sure to use new-style password hashing:
#   https://dev.mysql.com/doc/refman/5.7/en/password-hashing.html
#
  default: &default
    adapter: mysql2
    encoding: utf8
    pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
    username: dbuser
    password: dbpass
    socket: /var/run/mysqld/mysqld.sock

development:
  <<: *default
  database: UberEvaluation_development

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: UberEvaluation_test

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
#   DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
#   production:
#     url: <%= ENV['DATABASE_URL'] %>
#
production:
  <<: *default
  database: UberEvaluation_production
  username: UberEvaluation
  password: <%= ENV['UBEREVALUATION_DATABASE_PASSWORD'] %>
