Hi. I came across this repository recently and really enjoyed using the app (in development mode). However, a small problem I found was that the build command: npm run preview gives an error like so:

I think this issue was also referenced before here.

On a side note, the development mode mostly works. However, there's also a small bug in which the favorites list aren't getting updated even though redux is firing and the save state is being updated in local storage.

Anyway, great work so far.
