at Registry._get (http://localhost:3000/static/js/bundle.js:123625:13) please resolve issue in this LineChart.jsx file

I have successfully built this app. Listing some issues faced by me and how i solved it.

1> price is not defined error
Ans: use if (isFetching) return ; maybe you are trying to access before it fetches so this will prevent it., in the video ? is missing after cryptoDetails
or use this. { title: 'Price to USD', value: $ ${cryptoDetails?.price && millify(Number(cryptoDetails.price))}, icon: },

2> Cryptodetails for 24h is changed
sol: use this line in cryptodetails.jsx file { title: '24h Volume', value: $ ${cryptoDetails["24hVolume"] && millify(cryptoDetails["24hVolume"])}, icon: },

Tip: Console log data and match names of field fetched by api with the code and make changes accordingly

USE THIS UPDATED stats and generic stats

const stats = [
{ title: 'Price to USD', value: $ ${cryptoDetails?.price && millify(Number(cryptoDetails.price))}, icon: },
{ title: 'Rank', value: cryptoDetails?.rank, icon: },
{ title: '24h Volume', value: $ ${cryptoDetails["24hVolume"] && millify(cryptoDetails["24hVolume"])}, icon: },
{ title: 'Market Cap', value: $ ${cryptoDetails?.marketCap && millify(Number(cryptoDetails.marketCap))}, icon: },
{ title: 'All-time-high(daily avg.)', value: $ ${millify(Number((cryptoDetails?.allTimeHigh.price)))}, icon: },
];

const genericStats = [
{ title: 'Number Of Markets', value: cryptoDetails?.numberOfMarkets, icon: },
{ title: 'Number Of Exchanges', value: cryptoDetails?.numberOfExchanges, icon: },
{ title: 'Change', value: cryptoDetails?.change, icon : },
{ title: 'Total Supply', value: $ ${millify(Number((cryptoDetails?.supply.total)))}, icon: },
{ title: 'Circulating Supply', value: $ ${millify(Number((cryptoDetails?.supply.circulating)))}, icon: },
];

If chart is not from left to right then use this
const data = {
labels: coinTimestamp.reverse(),
datasets: [
{
label: "Price In USD",
data: coinPrice.reverse(),
fill: false,
backgroundColor: "#0071bd",
borderColor: "#0071bd",
},
],
};

here we are reversing values of array.

TIP: Go to my repo and copy the updated code wherever you are stuck 😉
3> History API should be written like this
getCryptoHistory:builder.query({
query: ({coinId,timePeriod}) => createRequest(/coin/${coinId}/history?timePeriod=${timePeriod})
})
4> ID has been changed to uuId so make changes in cryptocurrencies.jsx like this
5> Exchanges path is not paid in the api so you cant access with free api
6> LineChart.jsx not working? Copy it from my project ;)
If this helps then you may consider giving star to me 😊

Thank you buddy

const CryptoDetails = () => {
const { coinId } = useParams();
console.log(coinId);
