After I mint the NFTs successfully to Polygon, the metadata doesnât seem to upload for these files. When I was testing yesterday with smaller files it worked fine.
When I try the validate asset link from OpenSea I get:
{
âsuccessâ: false
}
.jscode1
let fs = require(âfsâ);
let axios = require(âaxiosâ);
let media = [âalbumcover.pngâ, âFung Ku.mp3â, âHoles.mp3â];
let ipfsArray = [];
let promises = [];
for (let i = 0; i < media.length; i++) {
promises.push(
new Promise((res, rej) => {
fs.readFile(`${__dirname}/export/${media[i]}`, (err, data) => {
if (err) rej();
ipfsArray.push({
path: `media/${i}`,
content: data.toString("base64"),
});
res();
});
})
);
}
Promise.all(promises).then(() => {
axios
.post("https://deep-index.moralis.io/api/v2/ipfs/uploadFolder", ipfsArray, {
headers: {
"X-API-KEY":
"API Key",
"Content-Type": "application/json",
accept: "application/json",
},
})
.then((res) => {
console.log(res.data);
})
.catch((error) => {
console.log(error);
});
});

let durations = [â1:56â, â3:05â];
