Encountering 'ReferenceError: zaius is not defined' Error in Frontend

[avelija1]

There is a 'ReferenceError: zaius is not defined' error on the frontend side:

This error occurs when in preview mode and specifically takes place in the '~\Foundation-spa-react-master\src\frontend\pages_app.tsx' file.

What does this do? I Just removed it and most things seemed to work as intended..?
