Provide a brief description of the functionality you're trying to implement and the issue you are running into.

I want to execute transaction with zksync2 go sdk. I implemented following code :

`
paymasterInput, err := utils.GetGeneralPaymasterInput(types.GeneralPaymasterInput{})
if err != nil {
return errors.Wrap(err, "failed to get paymaster input")
}

hash, err := c.Wallet.SendTransaction(context.Background(), &accounts.Transaction{
	To:              &contractAddress,
	Data:            calldata,
	PaymasterParams: &types.PaymasterParams{Paymaster: paymasterAddress, PaymasterInput: paymasterInput},
})
if err != nil {
	return errors.Wrap(err, "failed to send transaction")
}

_, err = c.Client.WaitMined(context.Background(), hash)
if err != nil {
	return errors.Wrap(err, "failed to wait mined")
}

`

I got : failed to EstimateFee: failed to query zks_estimateFee: virtual machine entered unexpected state. please contact developers and provide transaction details that caused this error. Error description: Assertion error: paymasterInput non zero

I was trying to execute on Sophon Testnet

It appears that the issue you're encountering with the ZKsync Go SDK is related to the paymasterInput being non-zero, which is causing the zks_estimateFee query to fail. This error typically indicates that there might be an issue with how the paymasterInput is being generated or used in your transaction.

Here are a few steps you can take to troubleshoot and potentially resolve this issue:

1. Verify paymasterInput Generation: Ensure that the paymasterInput is being generated correctly. You might want to check if the types.GeneralPaymasterInput{} is properly populated with all required fields before passing it to utils.GetGeneralPaymasterInput.

2. Check Paymaster Configuration: Verify that the paymasterAddress you are using is correct and that the paymaster is configured properly to accept transactions from your contract.

3. Review SDK and Documentation: Make sure you are using the latest version of the ZKsync Go SDK and review the relevant documentation for any updates or changes in how transactions and paymaster inputs should be handled.

4. Contact Support with Details: Since the error message suggests contacting developers, it would be helpful to provide them with the transaction details, including the paymasterInput and any other relevant configuration details, so they can help diagnose the issue more effectively.

For further assistance, you might want to visit the ZKsync developers discussions on Github where you can find more specific guidance or post your issue for more detailed help.

Hello, this issue might happen if the paymaster address is empty - what value are you setting it to?
