Pump.fun Create tokens blockchain decode data

Question

I get this metaplex program log in the blockchain (metaqbxxUerdq28cj1RbbAWkYQm3ybzjb6a8bt518x1s)

How do I decode it so I can get this token data?

At the moment I'm from this log 'Program data: G3KpTd7rY3YUUAAAAAU21va2luZyBHYW5nc3RlciBQaWcDAAAAU0dQQQwAAAGh0dHBzOi8vaXBmcy5pby9pcGZzL1FtWDFLU1ZWeEt3TDNmRktORTJ2YmZvdmNuYUs3a0E3UDZvOVBoNm83VDlQR1Sayl jIqddZ5MHb5i5554M127CJIdXepFn5OOqgc7Coz0B8boK9mw6bXgT83AhpeAbeS1DjAlCvNHpUSuosoPNpfj2BckBfcTh8yTCmA8J0eJdp/dtcJR/hMeQbZuU+qWI=' will only be able to get surface data without mint, user, bc...

You can get the metadata in the structured format.

export async function getMeta(conn: Connection, token: string) {
  try {
    const metaplex = Metaplex.make(conn);
    const mintAddress = new PublicKey(token);
    const metadataAccount = metaplex.nfts().pdas().metadata({ mint: mintAddress });

    const metadataAccountInfo = await conn.getAccountInfo(metadataAccount);

    if (metadataAccountInfo) {
      const meta = await metaplex.nfts().findByMint({ mintAddress: mintAddress });
      return new TokenMeta({
        address: meta.metadataAddress.toBase58(),
        mintAddress: token,
        mint: meta.mint,
        updateAuthorityAddress: meta.updateAuthorityAddress.toBase58(),
        json: meta.json ? JSON.stringify(meta.json) : "",
        jsonLoaded: meta.jsonLoaded,
        name: meta.name,
        symbol: meta.symbol,
        uri: meta.uri,
        isMutable: meta.isMutable,
        primarySaleHappened: meta.primarySaleHappened,
        sellerFeeBasisPoints: meta.sellerFeeBasisPoints,
        editionNonce: meta.editionNonce,
        creators: meta.creators,
        tokenStandard: meta.tokenStandard,
        collection: meta.collection,
        collectionDetails: meta.collectionDetails,
        uses: meta.uses,
        compression: meta.compression,
      });
    }
  } catch (err) {
    G.log("❗ get meta failed", err);
  }
  return null;
}

I hope you to please remember that getting the metadata with metaplex takes some delays. So while managing the result of the metadata you would rather to set some delays or retry when it returned the value of undefined or null.
