Vercel deployment auth.js not found

Thanks. I’m not entirely sure how these help solve the issue, however. No part of my code has changed – I am simply getting the following error when I try to deploy on Vercel: File not found: /vercel/path0/api/src/functions/auth.js

I tried upgrade my Redwood version to 8.4. However, I get the following error:

`[commonjs–resolver] Missing “./dist/toast” specifier in “@redwoodjs/web” package

22:16:03.662`

The solution offered in this link does not work, as I get the same error. And installing the react-hot-toast pacage directly does not work, as the above ./dist/toast specifier error occurred at deployment.
