Transaction simulation failed: Error processing Instruction 0: custom program error: 0x0

Question

I am using raydium sdk to add liquidity to the pair, I have created the transaction but whenever it gets approved from the phatom wallet an error occurs which is stated below.

Transaction simulation failed: Error processing Instruction 0: custom program error: 0x0
Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL invoke [1]
Program log: Allocate space for the associated token account

Allocate: account Address { address: 7hLSYuEhn7t1P62n9gpv2aG8peTtLvjSRKqSsk2MXa91, base: None } already in use
Program 11111111111111111111111111111111 failed: custom program error: 0x0
Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL consumed 8366 of 200000 compute units
Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL failed: custom program error: 0x0

I need help to fix this as I am unable to identify the issue.

Below is my function code which I am using in ReactJS with the help of Raydium SDK.

 const tokenReq = await solanaConnectionObj.getTokenAccountsByOwner(publicKey, { programId: TOKEN_PROGRAM_ID })
  const parsedTokenAccounts = await solanaConnectionObj.getParsedTokenAccountsByOwner(publicKey, {
    programId: TOKEN_PROGRAM_ID,
  })

  const tokenAccounts = []
  for (let index = 0; index < tokenReq.value.length; index++) {
    const rawResult = SPL_ACCOUNT_LAYOUT.decode(tokenReq.value[index].account.data)
    if (
      rawResult.mint.toString().toLowerCase() === tokenObj0.mint.toString().toLowerCase() ||
      rawResult.mint.toString().toLowerCase() === tokenObj1.mint.toString().toLowerCase() ||
      rawResult.mint.toString().toLowerCase() === RAYDIUM_LP_TOKEN_ACCOUNT.toLowerCase()
    ) {
      tokenAccounts.push({
        accountInfo: rawResult,
        pubkey: publicKey,
      })
    }
  }

  const transactionData = await Liquidity.makeAddLiquidityTransaction({
    poolKeys: RAYDIUM_POOL,
    userKeys: {
      tokenAccounts: tokenAccounts,
      owner: publicKey,
      payer: publicKey,
    },
    fixedSide: 'a',
    amountInB: new TokenAmount(tokenObj1, amount0.toWei().toString()),
    amountInA: new TokenAmount(tokenObj0, amount1.toWei().toString()),
    connection: solanaConnectionObj,
  })

  transactionData.transaction.feePayer = publicKey
  const latestBlockHashResult = await solanaConnectionObj.getRecentBlockhash('confirmed')

  transactionData.transaction.recentBlockhash = latestBlockHashResult.blockhash

  const signedTxs = await signTransaction(transactionData.transaction)
  const txids = await solanaConnectionObj.sendRawTransaction(signedTxs.serialize())

  return transactionData

It's hard to give a full answer without knowing more details about the makeAddLiquidityTransaction endpoint, but the error you're seeing is:

Allocate: account Address { address: 7hLSYuEhn7t1P62n9gpv2aG8peTtLvjSRKqSsk2MXa91, base: None } already in use

during the invocation of the Associated Token Account program, which creates new token accounts for users.

In your case, the error says that the account is already in use, so the transaction contains an unnecessary call to create the associated token account. This may be a bug in the Raydium SDK, or the RAYDIUM_LP_TOKEN_ACCOUNT address may be incorrect, causing the SDK to think you don't have the proper LP token account. You can hack around this by removing that first instruction if needed.
