Hi, we may need some more info here to get going.
Please could you make your project public and share the URL with us (step by step here how to give us access to your gitlab Unable to download resource)
when you encounter an error you can also use the developer tools to find where the issue is occurring (which is outlined here alongside other helpful JS tips https://docs.google.com/document/d/13jp0QAqQeFlYSjeZS0fDInvgaDzBXjGQNe4VNKbbNHQ/edit)
