enter image description here

I tried to figure out the collection id from the api i got an hex value but when i tried to convert that hex to numbers i got an undefined value here is my code i think the hex value which is outside the json is the number value

(async () => {
// Construct
const wsProvider = new WsProvider('wss://westmint-rpc.polkadot.io');
const api = await ApiPromise.create({ provider: wsProvider });

// Do something
  const ADDR = '5DTestUPts3kjeXSTMyerHihn1uwMfLj8vU8sqF7qYrFabHE';
const AccountId32 = '5GCCJthVSwNXRpbeg44gysJUx9vzjdGdfWhioeM7gCg6VyXf';
const u32 = '4';
// Retrieve the last timestamp
const collectionMetadataOf = await api.query.nfts.collectionMetadataOf.entries();
const accounts = api.query.nfts.collectionMetadataOf.entries();
console.log(`${collectionMetadataOf} `);
const obj = JSON.parse(`${collectionMetadataOf} `);
console.log(obj.data)

If you want to get the same values as you are getting with PolkadotJS UI try this snippet:

const collectionMetadataOf = await api.query.nfts.collectionMetadataOf.entries();
        collectionMetadataOf.forEach(([{ args: [id] }, value]) => {
        const metadata = JSON.parse(`${value}`);
        console.log(id.toHuman());
        console.log(metadata);
});

You can see more information and examples of how to parse the information with entries() in the docs: How do I use .entries()/.keys() on double maps?
