Answer 1

You can check the deployment logs from the EC2 itself.

Deployment logs are available in:

/opt/codedeploy-agent/deployment-root/deployment-logs/codedeploy-agent-deployments.log

Individual deployment logs can be found from the following location. Replace deployment-group-ID & deployment-ID with your actual values.

/opt/codedeploy-agent/deployment-root/deployment-group-ID/deployment-ID/logs/scripts.log

You can read more about CodeDeploy logs management from here. There is also an option to view the deployments logs from CloudWatch console using CloudWatch log agent. Refer this AWS blog for more information

Answer 2

Edit: After we saw more output from the scripts after using debugging (see below)

From the output it seems that your app does not compile because eslint found errors. That is default behaviour for apps created with create-react-app if I'm not mistaken.

I'd advice you to try and fix these errors in your dev environment first. Just starting the app by running your app_start script should do it. If you encounter errors you need help with, try asking new, specific questions here on SO.

(Optionally, if you don't want to fix the lint errors, you can tell eslint to ignore a line by adding // eslint-disable-next-line to the line before like the script mentions).

Debugging Tips Followed

Not directly an answer to your question, but you could consider adding this to your bash scripts to see more output:

#!/bin/bash
set -ex

Set -e stops your script on errors and -x prints out each command before it runs it so you have a bit of a stack trace.
