it uses client-side stuff so where you use it you need to use use client as it describes in its documentation

I have no idea where to start -- this error seems a bit cryptic? Attached is my not-found.jsx
This error is while doing a build, this doesn't happen with the development server
Selkirk RexOP
oh yeah
before each of htese errors, theres this:
TypeError: _react.default.createContext is not a function

right
i'm just not going to use it for now because it recommends making the layout a client component which i'd rather not do

i wouldn't do that either, but you can follow [this approach](https://github.com/Skyleen77/next-nprogress-bar#second-approach-wrap-in-a-use-client-providers-component-1) which doesn't require making your root layout a client component (which is against nextjs' convention)
