testnet createNft failed

[yuhj86]

run this example code, is ok on devnet, but got error on testnet

import { generateSigner, percentAmount, keypairIdentity } from "@metaplex-foundation/umi"
import { createNft, mplTokenMetadata } from "@metaplex-foundation/mpl-token-metadata"
import { createUmi } from "@metaplex-foundation/umi-bundle-defaults"
import { clusterApiUrl } from '@solana/web3.js'
import secret from 'PATH_TO_WALLET_ID.json' with { type: "json" }

const umi = createUmi(clusterApiUrl("devnet"))
  .use(keypairIdentity({
    publicKey: 'WALLET_ADDRESS',
    secretKey: new Uint8Array(secret)
  }))
  .use(mplTokenMetadata())
// Create the Collection NFT.
const collectionUpdateAuthority = generateSigner(umi);
const collectionMint = generateSigner(umi);

const tx = await createNft(umi, {
  mint: collectionMint,
  authority: collectionUpdateAuthority,
  name: "My Collection NFT",
  uri: "https://example.com/path/to/some/json/metadata.json",
  sellerFeeBasisPoints: percentAmount(9.99, 2), // 9.99%
  isCollection: true,
}).sendAndConfirm(umi);

console.log(tx)

Hey @yuhj86 testnet has not the latest versions of the program since testnet is not made for us developers but to test solana itself. You should use devnet or localnet instead for testing.

Thank you for explaining.

Having a similar problem, looks like devnet is down, getting error: failed to send transaction: Transaction simulation failed: Error processing Instruction 0: Failed to serialize or deserialize account data: Unknown at Connection.sendEncodedTransaction const connection = new Connection(clusterApiUrl('testnet'), "confirmed"); const umi = createUmi(connection) .use(walletAdapterIdentity(wallet)) .use(mplCandyMachine()); const mint = generateSigner(umi) await createNft(umi, { mint, name: 'My NFT', uri: 'https://example.com/my-nft.json', sellerFeeBasisPoints: percentAmount(5.5), }).sendAndConfirm(umi) const asset = await fetchDigitalAsset(umi, mint.publicKey)
