current situation

Rails app to AWS EC2 instancegit cloneAfterunicornI'm trying to start.

bundle exec unicorn_rails -c config/unicorn.rb -E production -D

When the above command is executed

master failed to start, check stderr log for details

I get the error.

what I want to know

Looking at the logNoMethodErrorI wonder if the specified method is not defined ... but I don't know the details and I can't figure out the source of the error.

Could you please explain the details of the error?
Thanks for your cooperation.

    NoMethodError: undefined method `fetch'for #

    The method called fetch is undefined. You say.
    Let's review the use of methods with that name

    Nice to meet you.

    I've never used Unicorn, so it's an imaginary answer, but I hope you find it helpful.
