Update Metadata of Metaplex NFT

Question

I have some problem in updating Metaplex NFT Metadata. I used @metaplex/js and this is my code.

import { programs } from '@metaplex/js';

export const updateMetadataV1 = async () => {
  let { metadata : {Metadata, UpdateMetadata, MetadataDataData, Creator} } = programs;
  let signer = loadWalletKey(keyfile);
  let nftMintAccount = new PublicKey("EC8gGdtVFDoTf3vEGbLvPp7SVWta2xQrs99iWMbaFrdE");
  let metadataAccount = await Metadata.getPDA(nftMintAccount);
  const metadat = await Metadata.load(solConnection, metadataAccount);
  let newUri = "https://arweave.net/my arweave address";
  if (metadat.data.data.creators != null) {
    const creators = metadat.data.data.creators.map(
      (el) =>
          new Creator({
              ...el,
          }),
    );
    let newMetadataData = new MetadataDataData({
      name: metadat.data.data.name,
      symbol: metadat.data.data.symbol,
      uri: newUri,
      creators: [...creators],
      sellerFeeBasisPoints: metadat.data.data.sellerFeeBasisPoints,
    })
    const updateTx = new UpdateMetadata(
      { feePayer: signer.publicKey },
      {
        metadata: metadataAccount,
        updateAuthority: signer.publicKey,
        metadataData: newMetadataData,
        newUpdateAuthority: signer.publicKey,
        primarySaleHappened: metadat.data.primarySaleHappened,
      },
    );
    let result = await sendAndConfirmTransaction(solConnection, updateTx, [signer]);
    console.log("result =", result);
  }
}

The transaction result has no error, it means transaction success. I checked it on Solana Explorer. But the metadata doesn't change. What's the matter?

Are sure that the pubkey from the keypair file has the update authority of the nft metadata account? You can check it on explorer from the nft metadata account. — rainbowemoji, Nov 20 '21 at 07:02
Yeah, I am sure all about your suggestion, I found a solution from https://github.com/metaplex-foundation/metaplex/issues/734#issuecomment-946818503 — Phoon Anan, Nov 20 '21 at 08:29
is it still an issue? Can you please show the transaction on slana explorer which is not showing an error? — Mark Sackerberg, May 23 '22 at 13:29

To Solve this issue this code can be used, This is a low-level code that uses the mpl-token-metadata npm package to call the on-chain updateMetadata Function.

import { Wallet } from "@project-serum/anchor";
import * as anchor from "@project-serum/anchor";
import {createUpdateMetadataAccountV2Instruction,DataV2,UpdateMetadataAccountV2InstructionArgs,UpdateMetadataAccountV2InstructionAccounts} from "@metaplex-foundation/mpl-token-metadata"
const fs = require("fs");

(async() => {
    // This is the Update Authority Secret Key
    const secretKey = fs.readFileSync(
        "/Users/pratiksaria/.config/solana/id.json",
        "utf8"
      );
      const keypair = anchor.web3.Keypair.fromSecretKey(
        Buffer.from(JSON.parse(secretKey))
      );
      const endpoint = "https://metaplex.devnet.rpcpool.com/";
  const connection = new anchor.web3.Connection(endpoint);

  const wallet = new Wallet(keypair);
  console.log("Connected Wallet", wallet.publicKey.toString());

  const TOKEN_METADATA_PROGRAM_ID = new anchor.web3.PublicKey(
    "metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s"
  );

  // You have to enter your NFT Mint address Over Here
  const mintKey = new anchor.web3.PublicKey("5iSxT33FyHWsnb8NYSytY17TTXfkFn62FiCyFVFxYhqY");

  const [metadatakey] = await anchor.web3.PublicKey.findProgramAddress(
    [
      Buffer.from("metadata"),
      TOKEN_METADATA_PROGRAM_ID.toBuffer(),
      mintKey.toBuffer(),
    ],
    TOKEN_METADATA_PROGRAM_ID
  );

  // BTW DeGods is my FAV collection although i cant afford one 
  const updated_data: DataV2 = {
    name: "DeGods",
    symbol: "DG",
    uri: "https://metadata.degods.com/g/4924.json",
    sellerFeeBasisPoints: 1000,
    creators: [
      {
        address: new anchor.web3.PublicKey(
          "CsEYyFxVtXxezfLTUWYwpj4ia5oCAsBKznJBWiNKLyxK"
        ),
        verified: false,
        share: 0,
      },
      {
        address: wallet.publicKey,
        verified: false,
        share: 100,
      },
    ],
    collection: null,
    uses: null,
  };

  const accounts:UpdateMetadataAccountV2InstructionAccounts = {
    metadata: metadatakey,
    updateAuthority: wallet.publicKey,
  }

  const args:UpdateMetadataAccountV2InstructionArgs = {
    updateMetadataAccountArgsV2: {
      data: updated_data,
      updateAuthority: wallet.publicKey,
      primarySaleHappened: true,
      isMutable: true,
    }
  }

  const updateMetadataAccount = createUpdateMetadataAccountV2Instruction(
  accounts,
  args
  );

  const transaction = new anchor.web3.Transaction()
  transaction.add(updateMetadataAccount);
  const {blockhash} = await connection.getLatestBlockhash();
  transaction.recentBlockhash = blockhash;
  transaction.feePayer = wallet.publicKey;
  const signedTx = await wallet.signTransaction(transaction);
  const txid = await connection.sendRawTransaction(signedTx.serialize());

  console.log("Transaction ID --",txid);

})()

let blockhashObj = await solConnection.getLatestBlockhash();
  updateTx.recentBlockhash = blockhashObj.blockhash;

  updateTx.sign(alice);

  let endocdeTransction = updateTx.serialize({
    requireAllSignatures: false,
    verifySignatures: false,
  });
  var signature = await solConnection.sendRawTransaction(endocdeTransction, {
    skipPreflight: false,
  });
