opensea-js v6.1.1 does not allow me to create orders on MATIC. Any ETA?

[munimdev]

Tried the new version to crate an offer, it's throwing this error Error: Creating orders on matic not yet supported by the SDK.

My code:

const { ethers } = require("ethers");
const { OpenSeaSDK, Chain } = require("opensea-js");

// This example provider won't let you make transactions, only read-only calls:
const provider = new ethers.providers.JsonRpcProvider(
  "https://mainnet.infura.io"
);

const wallet = new ethers.Wallet(
  "<key>",
  provider
);

const openseaSDK = new OpenSeaSDK(provider, {
  chain: Chain.Polygon,
  apiKey: "<API>",
});

// Token ID and smart contract address for a non-fungible token:
const { tokenId, tokenAddress } = {
  tokenId: "<id>",
  tokenAddress: "<address>",
};
// The offerer's wallet address:
const accountAddress = "<account address>";

const main = async () => {
  const offer = await openseaSDK.createBuyOrder({
    asset: {
      tokenId,
      tokenAddress,
    },
    accountAddress,
    // Value of the offer, in units of the payment token (or wrapped ETH if none is specified):
    startAmount: 1.2,
  });

  console.log("Offer created: ", offer);
};

main();

Any ETA on when we can expect to create offers? And is there currently a way to do this with the API? A working example would be very much appreciated.

Are you sure you're on v6.1.1? I would delete your node_modules and reinstall. What happens if you execute the cmd cat node_modules/opensea-js/package.json

You also have to pass the wallet to the 4th constructor arg of the library

Also, tried that. Getting the same error:

                throw new Error(`Creating orders on ${this.chain} not yet supported by the SDK.`);
                      ^

My code:

const { ethers } = require("ethers");
const { OpenSeaSDK, Chain } = require("opensea-js");

// This example provider won't let you make transactions, only read-only calls:
const provider = new ethers.providers.JsonRpcProvider(
  "https://mainnet.infura.io"
);

const wallet = new ethers.Wallet(
  "<Private Key>",
  provider
);

const openseaSDK = new OpenSeaSDK(
  provider,
  {
    chain: Chain.Polygon,
    apiKey: "<OpenSea API key>",
  },
  wallet
);

// Token ID and smart contract address for a non-fungible token:

};
// The offerer's wallet address:
const accountAddress = "<Public Address of my wallet>";

const main = async () => {
  const offer = await openseaSDK.createBuyOrder({
    asset: {
      tokenId,
      tokenAddress,
    },
    accountAddress,
    // Value of the offer, in units of the payment token (or wrapped ETH if none is specified):
    startAmount: 1.2,
  });

  console.log("Offer created: ", offer);
};

main();

Just checked the source code for opensea-js/lib/sdk.js. The issue is because of these lines of code:

//TODO: Make this function multichain compatible
if (this.chain != types_1.Chain.Mainnet && this.chain != types_1.Chain.Goerli) {
    throw new Error(`Creating orders on ${this.chain} not yet supported by the SDK.`);
}

Thanks, fixing this in patch version 6.1.2 which will get published this morning
