Currently, I tried to create a post app with Rails and deploy it with AWS, but if you try to launch Rails with the following command, an error is displayed.

Run command:

bundle exec moniicorn_rails -c config /unicorn.rb -e Production -D

Error message:

Master Failed to Start, Check Stderr Log for Details

If you check the error statement, it is like an image, but locally, it is moving without problems and thinks that there is a problem with GEM, but it is a state in which you should add any changes.
I would like to know if there is any problem if there is a problem.
