signBundle bundle used too little gas

[maooricio]

Hi, well I don't know if this provider is only for transfers transactions, if so, my question doesn't have a point. But, if this module was built to support contract interactions so I want to know if I am doing something wrong. I have the following code:

const GWEI = 10n ** 9n
const CHAIN_ID = 5
const FLASHBOTS_ENDPOINT = 'https://relay-goerli.flashbots.net'
const provider = new providers.InfuraProvider('goerli', process.env.INFURA_API_KEY)
const signer = Wallet.createRandom()
const flashbot = await FlashbotsBundleProvider.create(provider, signer, FLASHBOTS_ENDPOINT)
const valueToSendParsed = utils.parseEther('0.01')
const encodedData = '0x7ff36ab500000000000000000000000000000000000000000000000016498f36d4b30300000000000000000000000000000000000000000000000000000000000000008000000000000000000000000054a1c450e8cf7dcde904aa9340375ced46d1cc8c00000000000000000000000000000000000000000000000000000180b94bcbd00000000000000000000000000000000000000000000000000000000000000002000000000000000000000000b4fbf271143f4fbf7b91a5ded31805e42b2208d60000000000000000000000009fffb5a9f5c6a55fa802318ff49936e672399b56'

const signedTx = await flashbot.signBundle([
      {
        signer: wallet,
        transaction: {
          chainId: CHAIN_ID,
          // EIP 1559 transaction
          type: 2,
          value: valueToSendParsed,
          data: encodedData,
          maxFeePerGas: GWEI * 3n,
          maxPriorityFeePerGas: GWEI * 2n,
          gasLimit: 300000,
          to: process.env.ROUTER_CONTRACT_ADDRESS
        }
      }
   ])

The method signBundle always return body="{\"error\":{\"message\":\"bundle used too little gas, must use at least 42000\"}}", no matter if I increase the gas limit of the transaction. The data of the transaction is a swap of a DEX router. What am I doing wron? In advance thanks

Having the same issue, were you able to solve it?

[maooricio]

No yet, I am still waiting for an answer

[a180024]

was an error on my side, i didn't have enough funds for swapping

[maooricio]

It worked to you? If so, would you please share your code in order to see what is wrong with mine? Or do you see something wrong in the code that I shared?

[a180024]

variable names might be hard to see but generally the same other than maxPriorityFeePerGas and maxFeePerGas. what went wrong for me was i didn't have enough funds in the separate swap contract i was using

  const baseFeePerGas = block.baseFeePerGas; 
  const maxBaseFeePerGas = FlashbotsBundleProvider.getMaxBaseFeeInFutureBlock(
    baseFeePerGas,
    1
  );
