If I don't use the string updateAuthority: update_auth in nftData and i don't use Keypair.fromSecretKey(wallet2.secretKey) in web3jsVersionedTransaction.sign then the problem doesn't occur and the code works correctly. How to fix the problem and add updateAuthority correctly?

Try setting the update auth in a new instruction async function updateUpdateAuthority() { const mint = publicKey(""); // update with mint address await updateV1(umi, { mint, authority: umi.identity, newUpdateAuthority: publicKey(""), // new update auth primarySaleHappened: true, isMutable: true, }).sendAndConfirm(umi); } updateUpdateAuthority().then().catch();
