Hi, great project, could you let me know how to fix this?

var error = new Error(message);

Hello again, the bot is returning this error after calculating gas price in the function "calculate_gas_price". It seems that buy & sell functions requires BigNumber as input, but gas price is formated as string.

reason: 'invalid BigNumber string',
code: 'INVALID_ARGUMENT',
argument: 'value',
value: '5.000000001'

If i leave the calculate_gas_price function as following, it is able to run but i am getting strange results like failed txs and buys not in the right time (it executes after the original tx instead of before).

function calculate_gas_price(action, amount){
if (action==="buy"){
return amount.add(1);
}else{
return amount.sub(1);
}
}

Hello, as I can see there is a blacklist for the tokens we don't want to front run, isn't it better to had a whitelist? because there are a lot of tokens with high liquidity, I think it's better for the user to choose and whitelist tokens he or she wanted to front run. also please correct me if I'm wrong or mistaken. thank you.

Hello. First of all great project, thanks for creating it. When i try to run the bot it throws the following error:

TypeError: amount.add is not a function
at calculate_gas_price (D:\front-running-bot\bot.js:16:44)
at D:\front-running-bot\bot.js:173:31
at processTicksAndRejections (node:internal/process/task_queues:96:5)

What i am missing ?

reason: 'invalid BigNumber string',
code: 'INVALID_ARGUMENT',
argument: 'value',
value: '5.000000001'

th e returning this error after the execution of calculate maybe the error is in buy fonction because he says "prepare to buy" and returning this error

the sellToken function always approve first, so it's always come out that buy & sell in different blocks.
Can we put both of the transaction in the same block ?
