error: 'execution reverted',

When I construct a transaction, the transaction is to send a data to my personal contract through my account. Then simulate this transaction through the eth_callBundle method of flashbots, but the response I received shows an error, so I would like to ask you to help solve the problem, or point out the reason for the error, thank you for your help.
Below is my code and error message。

```
const Tx = {
to: my_contract.address,
from: Wallet.address,
data: Payload,
chainId: 1,
maxPriorityFeePerGas: 0,
maxFeePerGas: nextBaseFee,
gasLimit: 250000,
nonce: nonce + 1,
type: 2,
};
console.log(Tx);
const TxSigned = await Wallet.signTransaction(Tx);
const signedTxs = [TxSigned];
const simulatedResp = await callBundleFlashbots(signedTxs, targetBlockNumber);
```

the response is :
```
