Error listing NFT: Request failed with status code 500

[saurabhkaplas05]

I created a route which aims to list NFTs using OpenSea: `router.post('/sell', async (req, res) => {
const { tokenId, price } = req.body;

if (!tokenId || !price || !privateKey || !account) {
    return res.status(400).json({ error: 'Token ID, price, private key, and account address are required.' });
}

try {
    const priceInWei = web3.utils.toWei(price.toString(), 'ether');
    const currentTime = Math.floor(Date.now() / 1000);
    const endTime = currentTime + (60 * 60 * 24);

    const listingParameters = {
        offerer: account,
        offer: [{
            itemType: 2, 
            token: contractAddress,
            identifierOrCriteria: tokenId,
            startAmount: "1",
            endAmount: "1"
        }],
        consideration: [{
            itemType: 0, 
            token: "0x0000000000000000000000000000000000000000",
            identifierOrCriteria: "0",
            startAmount: priceInWei,
            endAmount: priceInWei,
            recipient: account
        }],
        startTime: currentTime,
        endTime: endTime,
        orderType: 0, 
        zone: "0x00000000000000adc04c56bf30ac9d3c0aaf14dc", 
        zoneHash: "0x0000000000000000000000000000000000000000000000000000000000000000",
        salt: web3.utils.randomHex(32),
        conduitKey: "0x0000007b02230091a7ed01230072f7006a004d60a8d4e71d599b8104250f0000",
        totalOriginalConsiderationItems: 1,
        counter: 0
    };

    const orderHash = web3.utils.sha3(JSON.stringify(listingParameters));
    const signature = web3.eth.accounts.sign(orderHash, privateKey);

    const listing = {
        parameters: listingParameters,
        signature: signature.signature,
        protocol_address: '0x00000000000000adc04c56bf30ac9d3c0aaf14dc', 
    };

    const apiUrl = `https://api.opensea.io/v2/orders/sepolia/seaport/listings`;
    const options = {
        method: 'POST',
        url: apiUrl,
        headers: {
            'accept': 'application/json',
            'content-type': 'application/json',
            'X-API-KEY': process.env.OPENSEA_API_KEY,
        },
        data: listing
    };

    const response = await axios.request(options);
    console.log('Listing response:', response.data);
    res.status(200).json({ message: 'NFT listed successfully', data: response.data });

} catch (error) {
    console.error('Error listing NFT:', error.message);
    if (error.response) {
        console.error('Full error details:', error.response.data);
    }
    res.status(500).json({ error: 'Failed to list NFT.', details: error.message });
}

});
but it is throwing me an error:Error listing NFT: Request failed with status code 500
Full error details: {
errors: [
