Gas estimation for a method

[fricpto]

Hello,I have a hardhat project that have a file that does this const arbitrage = new ethers.Contract(config.PROJECT_SETTINGS.ARBITRAGE_ADDRESS, IArbitrage.abi, provider); and it is imported in another js file and that file has a function that wants to estimate gas for a specific function inside the contract.sol file:

const account = new ethers.Wallet(process.env.PRIVATE_KEY, provider)
        const arbitrageWithSigner = arbitrage.connect(account);
const estimatedGasLimit = await arbitrageWithSigner.executeTrade.estimateGas(
            [await _exchangePath[0].router.getAddress(), await _exchangePath[1].router.getAddress()],
            [_token0.address, _token1.address],
            _poolFee,
            borrowAmount
            // ethers.parseUnits("1", _token0.decimals) Use a nominal amount for estimation
        );

I have logged the method estimateGas() and the executeTrade() they both exist

typeof arbitrageWithSigner.executeTrade: function
typeof arbitrageWithSigner.executeTrade.estimateGas: function

I also checked for executeTrade() method in my abi and it exist but I'm getting this error:⚠️ Profitability check failed: Cannot read properties of undefined (reading 'executeTrade')"},I'm using Ethers version: 6.15.0,I logged it to make sure that I'm correct.I'm using executeTrade() in an another function in the same file and I'm not getting any error from it.
Now what is the correct way to estimateGas()?
