我在更新 Metaplex NFT 元数据时遇到了一些问题。我使用了@metaplex/js，这是我的代码。

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);
  }
}

交易结果没有错误，说明交易成功。我在 Solana Explorer 上检查了它。但元数据不会改变。怎么了？
