Correct answer & explanation
✓
The file path defined in the appspec.yml for the lifecycle hook
The 'ScriptMissing' error in CodeDeploy indicates that the script file specified in the appspec.yml for a lifecycle event hook is not found at the expected path. The engineer should verify the file path defined in the appspec.yml to ensure it points to an existing executable script on the instance.
