Problems starting application deployment in RAILS 7 with capistrano - ruby-on-rails

Question

I was following a tutorial to test how to deploy an application in Rails but when I tried to run it, it generated several errors that I was solving, first I clarify that I am working locally from windows, and the server I am using as a target for testing is an ubuntu 18 instance of AWS. However I put the unicorn gem with this code in the gemfile.

The error that generates me in the deployment is this:

The truth is that I have tried to look for several solutions but I can't find the way to start the deployment and I am stuck in this error, in which I can't find any information.
the code for my deploy.rb is this:
# config valid only for current version of Capistrano
lock '3.17.1'
def deploysecret(key)
#deploy_secrets_yml ||= YAML.load_file('config/deploy-secrets.yml')[fetch(:stage).to_s]

end
