TokenAccountNotFoundError in getOrCreateAssociatedTokenAccount

Question

I want to transfer custom spl-token by '@solana/web3.js'.

I call a function getOrCreateAssociatedTokenAccount. It returns TokenAccountNotFoundError

  const connection = new Connection('https://api.devnet.solana.com', 'confirmed');
  const adminPubKey = new PublicKey(my wallet publicKey);
  const mintAccount = await getMintAccount(tokenId);
  const { signTransaction } = useWallet();

  const adminTokenAccount = await findATA(
    connection,
    adminPubKey,
    new PublicKey(mintAccount.toString()),
    adminPubKey,
    signTransaction, // 
  );

const findATA = async (connection, payer, tokenMintAddress, walletAddress, signTransaction) => {
  return await getOrCreateAssociatedTokenAccount(
    connection,
    payer,
    tokenMintAddress,
    walletAddress,
    signTransaction,
  );
};

it always returns null.

Answer 1

The 5th argument of the getOrCreateAssociatedTokenAccount function is optional and when used is a boolean type that specifies whether or not the owner of the ATA is a PDA. You typically don't need more than 4 arguments but when you do use the 5th it should be a bool and wouldn't match signTransaction here.

Call it like this instead:

return await getOrCreateAssociatedTokenAccount(
    connection,
    payer,
    tokenMintAddress,
    walletAddress,
  );
