how to create a transaction to burn SPL tokens in react app? - solana

Question

I wrote a function burnSplToken which takes two inputs:
(account(wallet address): string, {account(token address): string, amount: number(token amount)})
I am trying to create a transaction to burn specific amount of tokens. But it's giving me a buffer error at the getOrCreateAssociatedTokenAccount function saying buffer not found error. What am I doing wrong here? I am using react for the frontend.
export const burnSplToken = async (walletAddress, assetAddress) => {
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
let senderAddress = new PublicKey(walletAddress)
const mintPubkey = new PublicKey(assetAddress.tokenAddress);
let ataSender = await getOrCreateAssociatedTokenAccount(
connection, // connection
senderAddress, // fee payer
mintPubkey, // mint
senderAddress // owner,
);
console.log(`ATASender: ${ataSender}`);
// calculate ATA
let ata1 = await getAssociatedTokenAddress(
mintPubkey, // mint
senderAddress // owner
);
const message = `Sign below to authenticate with Rifters Adventure`;
const encodedMessage = new TextEncoder().encode(message);
const signedMessage = await window.solana.signMessage(encodedMessage, "utf8");
let blockhash = (await connection.getLatestBlockhash('finalized')).blockhash;
let tx = new Transaction().add(
createBurnCheckedInstruction(
ataSender.address, // token account
mintPubkey, // mint
senderAddress, // owner of token account
1e9, // amount, if your deciamls is 8, 10^8 for 1 token
9 // decimals
)
);
tx.recentBlockhash = blockhash;
tx.feePayer = senderAddress
const signedTransaction = await window.solana.signTransaction(tx);
console.log("signedTransaction", signedTransaction);
const signature = await connection.sendRawTransaction(signedTransaction.serialize());
console.log(signature)
}
