I get this error when i run heroku run rake db:migrate in production

I get this error when i run heroku run rake db:migrate in production.

is deprecated and will be removed in Rails 5.1.
Please use
config.public_file_server.enabled = true
(called from block in at /app/config/environments/production.rb:25)

I have tried some solution here on stackoverflow but i can't fix the problem.

Here is my production.rb file

Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.

# Code is not reloaded between requests.
config.cache_classes = true

# Eager load code on boot. This eager loads most of Rails and
# your application in memory, allowing both threaded web servers
# and those relying on copy on write to perform better.
# Rake tasks automatically ignore this option for performance.
config.eager_load = true

# Full error reports are disabled and caching is turned on.
config.consider_all_requests_local = false
config.action_controller.perform_caching = true

# Enable Rack::Cache to put a simple HTTP cache in front of your application
# Add `rack-cache` to your Gemfile before enabling this.
# For large-scale production use, consider using a caching reverse proxy like
# NGINX, varnish or squid.
# config.action_dispatch.rack_cache = true

# Disable serving static files from the `/public` folder by default since
# Apache or NGINX already handles this.
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?

# Compress JavaScripts and CSS.
config.assets.js_compressor = :uglifier
# config.assets.css_compressor = :sass

# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = true

# Asset digests allow you to set far-future HTTP expiration dates on all assets,
# yet still be able to expire them through the digest params.
config.assets.digest = true

# `config.assets.precompile` and `config.assets.version` have moved to config/initializers/assets.rb

# Specifies the header that your server uses for sending files.
# config.action_dispatch.x_sendfile_header = 'X-Sendfile' # for Apache
# config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for NGINX

# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
config.force_ssl = true

# Use the lowest log level to ensure availability of diagnostic information
# when problems arise.
config.log_level = :debug

# Prepend all log lines with the following tags.
# config.log_tags = [ :subdomain, :uuid ]

# Use a different logger for distributed setups.
# config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)

# Use a different cache store in production.
# config.cache_store = :mem_cache_store

# Enable serving of images, stylesheets, and JavaScripts from an asset server.
# config.action_controller.asset_host = 'http://assets.example.com'

# Ignore bad email addresses and do not raise email delivery errors.
# Set this to true and configure the email server for immediate delivery to raise delivery errors.
# config.action_mailer.raise_delivery_errors = false

# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation cannot be found).
config.i18n.fallbacks = true

# Send deprecation notices to registered listeners.
config.active_support.deprecation = :notify

# Use default logging formatter so that PID and timestamp are not suppressed.
config.log_formatter = ::Logger::Formatter.new

# Do not dump schema after migrations.
config.active_record.dump_schema_after_migration = false

Yes, replace the deprecated code with this:

 config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
