Issues trying to add a custom chain to the configureChains()

[auditism]

Hi everyone,
I am currently trying to add a custom chain to my wagmi config in next.js, but I am getting this error; TypeError: Cannot read properties of undefined (reading 'infura'), the same setup works when I am using the defaults chains so I am definitely adding the custom chain the wrong way, I'll share the faulty bits of my code

//_app.js
import { createClient, configureChains,, WagmiConfig } from "wagmi"
import { auroraChain } from "../constants"
import { infuraProvider } from 'wagmi/providers/infura'

const { provider, webSocketProvider, chains } = configureChains(
    [auroraChain]
    ,  [infuraProvider({ rpc: chain => ({ http: chain.rpcUrls.default }) })]
)

const { connectors } = getDefaultWallets({
    appName: "My RainbowKit App",
    chains,
})
....
//auroraChain
import { Chain } from "wagmi"

const auroraChain: Chain  = {
    id: 1313161555,
    name: "Aurora",
    network: "aurora testnet",
    nativeCurrency: {
        decimals: 18,
        name: "Ethereum",
        symbol: "ETH",
    },
    rpcUrls: {
        default: "https://aurora-testnet.infura.io/v3/xxx"
    },
    blockExplorers: {
        default: { name: "aurorascan", url: "https://testnet.aurorascan.dev/" },
    },
    testnet: true,
}
export default auroraChain

Does anyone know what I might have to fix in order to get it right ? any leads greatly appreciated !
