Description

This change has been to ensure that users receive accurate exit codes,
the CLI will now display any errors that occur and exit with the appropriate exit code (e.g., 1 for errors, 0 for success). This allows users to effectively handle error conditions and automate tasks based on the CLI's exit status.
