TypeError: calling a contract method in v6

[suchakpk]

I got this 👇 error while I try to run my code.

`C:\Users\Admin\Desktop\arbitrage flashloan\uniswapV3\node_modules\ethers\lib.commonjs\utils\errors.js:114
error = new TypeError(message);
^

Here is my full code:

`const ethers = require("ethers");

const {abi:QuoterABI,} = require("@uniswap/v3-periphery/artifacts/contracts/lens/Quoter.sol/Quoter.json");

const provider = new ethers.JsonRpcProvider("...........");

async function getPrice(addressFrom,addressTo,amountInHuman){
const quoterAddress = "0xb27308f9F90D607463bb33eA1BeBb41C27CE5AB6";
const quoterContract = new ethers.Contract(quoterAddress,QuoterABI,provider);
const amountIn = ethers.parseUnits(amountInHuman,6);
const quoteAmountOut = await quoterContract.callStatic.quoteExactInputSingle(addressFrom,addressTo,3000,amountIn.toString(),0);
//const amount = ethers.formatUnits(quoteAmountOut.toString(),18);
return quoteAmountOut;
}

const main = async () => {
const addressFrom = "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"; // USDC
const addressTo = "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"; // WETH
const amountInHuman = "1651";
const amountOut = await getPrice(addressFrom,addressTo, amountInHuman);
console.log(amountOut);
}

main();`

In v6, the name of the method comes first, so you should use:

contract.quoteExactInputSingle.staticCall(...)

Let me know if you have any further issues. :)

I did same as you told. But after that I face new error as follows:
`C:\Users\Admin\Desktop\arbitrage flashloan\uniswapV3\node_modules\ethers\lib.commonjs\utils\errors.js:138
throw makeError(message, code, info);

It looks like you are passing in a URL as your network name. It might be easier for you to use new ethers.AlchemyProvider("mainnet", "Xx2DxgFI1HX7k7gU4AdZov9xCOghZiPf') (that API key was taken from your above error)

Now this I got:
`C:\Users\Admin\Desktop\arbitrage flashloan\uniswapV3\client\GetUniswapPrices.js:11
const quoteAmountOut = await quoterContract.quoteExactInputSingle.callStatic(addressFrom,addressTo,3000,amountIn.toString(),0);
^

staticCall (not callStatic) ;)
