創建 metaplex 元數據帳戶時出現索引超出范圍錯誤

Question

為什么在嘗試使用 @ createCreateMetadataAccountV2Instruction @metaplex-foundation/mpl-token-metadata庫中的 createCreateMetadataAccountV2Instruction 創建元數據帳戶時出現以下錯誤？

SendTransactionError: failed to send transaction: Transaction simulation failed: Error processing Instruction 0: Program failed to complete

    'Program log: Instruction: Create Metadata Accounts v2',
    "Program log: panicked at 'range end index 36 out of range for slice of length 0', program/src/utils.rs:231:27",        
    'Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s consumed 6223 of 1400000 compute units',

    'Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s failed: Program failed to complete'
  ]
}

這是我的代碼：

import {
  createCreateMetadataAccountV2Instruction,
  PROGRAM_ID,
} from '@metaplex-foundation/mpl-token-metadata'
import {
  Connection,
  Keypair,
  PublicKey,
  sendAndConfirmTransaction,
  Transaction,
} from '@solana/web3.js'

export const addMetadataToToken = async (
  connection: Connection,
  tokenMint: PublicKey,
  tokenOwner: Keypair,
  name: string,
  symbol: string,
  arweaveLink: string
) => {
  const seed1 = Buffer.from('metadata', 'utf8')
  const seed2 = PROGRAM_ID.toBuffer()
  const seed3 = tokenMint.toBuffer()
  const [metadataPDA, _bump] = PublicKey.findProgramAddressSync(
    [seed1, seed2, seed3],
    PROGRAM_ID
  )
  const accounts = {
    metadata: metadataPDA,
    mint: tokenMint,
    mintAuthority: tokenOwner.publicKey,
    payer: tokenOwner.publicKey,
    updateAuthority: tokenOwner.publicKey,
  }
  const dataV2 = {
    name,
    symbol,
    uri: arweaveLink,
    // we don't need these
    sellerFeeBasisPoints: 0,
    creators: null,
    collection: null,
    uses: null,
  }
  const args = {
    createMetadataAccountArgsV2: {
      data: dataV2,
      isMutable: true,
    },
  }
  const ix = createCreateMetadataAccountV2Instruction(accounts, args)
  const tx = new Transaction()
  tx.add(ix)
  const txid = await sendAndConfirmTransaction(connection, tx, [tokenOwner])
  console.log(txid)
}

原來我是在嘗試為 devnet 上的令牌創建元數據，但正在為Connection類使用 mainnet-beta rpc 端點。 因此，我試圖為其創建元數據的令牌不存在。
