Error when running the app

[cryptoB0T]

not sure why we're getting this error:

Server Error
Error: Cannot read properties of undefined (reading 'config')

This error happened while generating the page. Any console logs will be displayed in the terminal window.
Source
src/config.ts (12:2) @ eval

  10 | export const chain = arbitrumSepolia;
  11 | export const config = createConfig(
> 12 | {
     |^
  13 |   // this is for requests to the specific chain RPC
  14 |   rpcUrl: "/api/rpc/chain/" + chain.id,
  15 |   signerConnection: {

steps to reproduce:

1. clone repo
2. add env vars
3. copy to .env.local
4. install deps with yarn
5. run app yarn dev

could there be something we're missing?
