Error: API Error 400: Protocol Address is a required field.

[JJSEONG]

I am currently using createSellOrder of opensea-sdk. The listing, which worked fine just a few days ago, is currently not running because there is no protocol address. How can i solve this error? Below is the code I am currently using. If you have solved the same error or know, please reply.

const expirationTime = Math.round(Date.now() / 1000 + 60 60 24); const listing = await getSeaport().createSellOrder({ asset: { tokenId, tokenAddress: REACT_APP_ETHEREUM_MINTING_CONTRACT_ADDRESS, }, accountAddress: account, startAmount: price, endAmount: price, expirationTime, });

Please update to the latest version, v5

[JJSEONG]

I have already updated to version 5. Still, the error continues to occur. "opensea-js": "^5.0.0",

[JJSEONG]

I've solved this problem!! After updating to v5, deleting node_modules and installing again solved the error. Thank you for your reply.

[creed-dev]

I also get this error in v5.0.0 even after removing and installing node_modules. Does anyone have a solution?

[ryanio]

@creed-dev please try with v6, and please share a code snippet to recreate so we can see the problem, the protocol address should be supplied by the SDK by default

@ryanio When i use v6: Firstly: I can't use HDWalletProvider and get "Error: Either a provider or custom signer with provider must be provided." Secondly: When i use JsonRpcProvider, i get:

As far as I understand, I need to sign a transaction to put an item up for sale. And for this I need to use HDWalletProvider as before.

Code:

require('dotenv').config();
const OpenSea = require("opensea-js");
const Web3 = require('web3');
const logger = require("./logger");
const ethers = require("ethers");

const {
    NETWORK,
    INFURA_KEY,
    NFT_CONTRACT_ADDRESS
} = process.env;

const OpenSeaSDK = OpenSea.OpenSeaSDK;

async function listing(tokenId, to, price) {
    try {
        logger.log('info', `Start listing function for token ID ${tokenId}`);

        const provider = new ethers.providers.JsonRpcProvider(
            "https://" + NETWORK + ".infura.io/v3/" + INFURA_KEY
        );

        const seaport = new OpenSeaSDK(
            provider,
            {
                chain: "goerli"
            }
        );

        tokenId = tokenId.toString();
        const priceOnWei = price.toString();
        const priceOnEth = Number(Web3.utils.fromWei(priceOnWei, 'ether')).toFixed(10);

        logger.log('info', `Request to OpenSea API for token ID ${tokenId}`);

        await seaport.createSellOrder({
            asset: {
                tokenId: tokenId,
                tokenAddress: NFT_CONTRACT_ADDRESS
            },
            startAmount: priceOnEth,
            accountAddress: to
        });
    } catch (err) {
        throw err;
    }
}

module.exports = {listing};
