Issue Summary

Faild to send userOp

Error Logs & Messages

I want to burn an NFT generated from a Thirdweb template using Bincomy.

I successfully created a SmartWallet by following the documentation.

However, I encountered the following error when trying to send the user operation to burn the NFT.

ERROR   Error occurred when sending UserOp: SizeExceedsPaddingSizeError: Hex size (65) exceeds padding size (64).

  tx: txData
) => {
  try {
    console.log('========================================== [SEND USEROP START] =============================================')
    console.log("build userOp:");

    const userOpResponse = await smartWallet!.sendTransaction(tx, {
      paymasterServiceData: { mode: PaymasterMode.SPONSORED },
    });
    const { transactionHash } = await userOpResponse.waitForTxHash();
    console.log("Transaction Hash", transactionHash);

    // get receipt
    const userOpReceipt = await userOpResponse.wait(5);
    console.log("userOpReceipt", userOpReceipt);
    console.log('========================================== [SEND USEROP END] =============================================')

    return userOpReceipt;
  } catch (err: any) {
    console.error("Error occurred when sending UserOp:", err);
    return null;
  }
};

Here is the code for generating the encoded data.

    const sdk = await createThirdWebSdk(TW_SECRET_KEY!, keyId);
    // get contract info
    const contract = await sdk.getContract(NFT_CONTRACT_ADDRESS);

    const encodeData = encodeFunctionData({
      abi: contract.abi,
      functionName: "burn",
      args: [tokenId],
    });

    const tx:TxData = {
      to: NFT_CONTRACT_ADDRESS, 
      data: encodeData
    }

    const receipt = await sendUserOp(smartWallet, tx);

Hi @HarukiKondo can you please update to latest version of the Biconomy SDK and try again ?

Maybe you can share how you are creating the "smartWallet" as well.
