'ElasticSearch deployment issue: NameError: uninitialized constant Elasticsearch

I am deploying my rails app via AWS. During the deployment I get the following error.

Automatic configuration of the sidekiq middleware is no longer done. Please see: https://github.com/mhenrixon/sidekiq-unique-jobs/blob/master/README.md#add-the-middleware

This version deprecated the following sidekiq_options

sidekiq_options lock_args: :method_name

It is now configured with:

sidekiq_options lock_args_method: :method_name

This is also true for Sidekiq.default_worker_options

We also deprecated the global configuration options:

default_lock_ttl

default_lock_ttl=

default_lock_timeout

default_lock_timeout=

The new methods to use are:

lock_ttl

lock_ttl=

lock_timeout

lock_timeout= Removing intermediate container 058b1862fa23 ---> d58eac1f9787 Step 22/28 : COPY --chown=app:app . . ---> f91e7b24a602 Step 23/28 : RUN bundle exec rake assets:precompile ---> Running in 49531771f9ca rake aborted!

The file referenced in the line below the error is:

if Rails.env == 'production'
  url = ENV["ELASTICSEARCH_URL"]
  transport_options = { request: { timeout: 250 } }
  options = { hosts: url, retry_on_failure: true, transport_options: transport_options }
  Searchkick.aws_credentials = {
    access_key_id: ENV["AWS_ACCESS_KEY_ID"],
    secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"],
    region: "eu-west-1"
  }
  
  Searchkick.client = Elasticsearch::Client.new(options)
end

Can someone please help me to understand what this error means.

Thanks in advance for any help.
