Unexpected error when create associated token account.

[joeuan]

Summary

I'm trying to create ATA account for user wallet when not exist (for token claim process). Only got 'Unexpected error', and hard to debug.
Here is the code:

import {
  PublicKey,
  Connection,
  clusterApiUrl,
  Transaction,
  TransactionInstruction
} from '@solana/web3.js'
import {
  ASSOCIATED_TOKEN_PROGRAM_ID,
  createAssociatedTokenAccountInstruction,
  getAccount,
  getAssociatedTokenAddressSync,
  TOKEN_PROGRAM_ID
} from '@solana/spl-token'

const getAssociatedTokenInstruction = async (
  connection: Connection,
  userPK: PublicKey,
  tokenContractPK: PublicKey,
  owner: PublicKey,
  associatedToken: PublicKey
): Promise<TransactionInstruction | null> => {
  try {
    await getAccount(connection, associatedToken, 'confirmed')
    return null
  } catch (e) {
    if (typeof e === 'object' && (e as any).name === 'TokenAccountNotFoundError') {
      return createAssociatedTokenAccountInstruction(
        userPK,
        associatedToken,
        owner,
        tokenContractPK,
        TOKEN_PROGRAM_ID,
        ASSOCIATED_TOKEN_PROGRAM_ID
      )
    } else {
      throw e
    }
  }
}

const tokenContract = 'the token contract address'
const provider = window.phantom.solana
const userPK = provider.publicKey
const tokenContractPK = new PublicKey(tokenContract)
const connection = new Connection(clusterApiUrl('devnet'), {
  commitment: 'confirmed'
})
const { lastValidBlockHeight, blockhash } = await connection.getLatestBlockhash('finalized')
const transaction = new Transaction({
  feePayer: userPK,
  blockhash,
  lastValidBlockHeight
})
const userAssociatedToken = getAssociatedTokenAddressSync(tokenContractPK, userPK, false)
const initUserTokenAccountInstruction = await getAssociatedTokenInstruction(
  connection,
  userPK,
  tokenContractPK,
  userPK,
  userAssociatedToken
)
if (initUserTokenAccountInstruction) {
  transaction.add(initUserTokenAccountInstruction)
}
const result = await provider.signAndSendTransaction(transaction)
// -> GOT ERROR Error: Unexpected error
console.log(result)
