Error: Execution reverted

Hi, Thanks for the tutorial on flashbots. I'm able to send bundle to flasbots goerli relayer but I'm getting `error: execution reverted`

Code:
```
async function main() {
const flashbotsProvider = await FlashbotsBundleProvider.create(provider, Wallet.createRandom(), FLASHBOTS_RELAY_GOERLI)
const block = await provider.getBlock("latest");
const maxBaseFeeInFutureBlock = FlashbotsBundleProvider.getMaxBaseFeeInFutureBlock(block.baseFeePerGas, 1);
const priorityFee = GWEI.mul(50);

const transactions = [
{
transaction: {
chainId: CHAIN_ID,
type: 2,
value: ETHER.div(100).mul(3),
gasLimit: 50000,
data: "0x1249c58b",
maxFeePerGas: priorityFee.add(maxBaseFeeInFutureBlock),
maxPriorityFeePerGas: priorityFee,
to: "0x20EE855E43A7af19E407E39E5110c2C1Ee41F64D",
},
signer: wallet,
}
]

provider.on('block', async (blockNumber) => {
console.log(blockNumber);

const response = await flashbotsProvider.sendBundle(transactions, blockNumber + 1)
console.log(await response.simulate())

if ('error' in response) {
console.log(response.error)
return
}

})

}
```

`console.log(await response.simulate())` outputs:

```

}
],

}
```

What could be the reason for such error ?
