Ruby on Rails app runs only as a root user and errors out when run as ec2-user-CodePudding

Background: I have a ruby application in an EC2 instance running Amazon Linux 2. My application is using Ruby 2.7.6. I am trying to run the application as ec2-user. When I run bundle install the packages load fine but error our when I run rails s command.

But when I run the application as root I don't face this error and the application is running fine.

But I need this to run for ec2-user and webapp users because during the deployment the pipeline is executing the command with webapp user and it errors out with a similar error.

Please advice on how to bypass this.

This issue is a known bug in the mail gem (see here).

You should make sure to use the previous version - 2.7.1.
