Vue js build issue

[rajinder-mck]

I have a legacy vue js project that works with node js version v14.15.5
it was working absolutly fine earlier now when I am trying to run it locally or trying to build prod build getting below errors

Syntax Error: SassError: 2 arguments required, but only 1 was passed.
╷
28 │ height: rem(4);
│ ^^^^^^

Syntax Error: SassError: expected selector.

I have tried to start fresh by clone project on fresh location of my mac laptop still getting this same error

can anyone help me to identify the issue
