Hello @JohnTan38, the issue is one resulting from your Windows setup. The character \r that you see displayed in your error messages is "carriage return", which means the Unix subsystem/layer you are using does not handle the Windows end-of-line character correctly.

The easiest fix is to save the affected files (docker files, etc.) in text editors which allow you to configure the end-of-line character, and make sure it is set to Unix.
