[Ethereum] tx fee (2.11 ether) exceeds the configured cap (1.00 ether), how to bypass default cap

It seems like you are trying to use the wrong getAmountsOut function:

// performs chained getAmountOut calculations on any number of pairs
function getAmountsOut(address factory, uint amountIn, address[] memory path) internal view returns (uint[] memory amounts) {
    require(path.length >= 2, 'PancakeLibrary: INVALID_PATH');
    amounts = new uint[](path.length);
    amounts[0] = amountIn;
    for (uint i; i < path.length - 1; i++) {
        (uint reserveIn, uint reserveOut) = getReserves(factory, path[i], path[i + 1]);
        amounts[i + 1] = getAmountOut(amounts[i], reserveIn, reserveOut);
    }
}

This function is marked as internal so it can only be called inside this contract or any contract that derived from the PancakeRouter contract. The right function to call would be this which is also located in the PancakeRouter contract:

function getAmountsOut(uint amountIn, address[] memory path) public pure virtual override returns (uint[] memory amounts) {
    return PancakeLibrary.getAmountsOut(factory, amountIn, path);
}

To give you an example on how to use it with Javascript:

const router = new ethers.Contract('0x10ED43C718714eb63d5aA57B78B54704E256024E', [
'function swapExactETHForTokens(uint amountOutMin, address[] calldata path, address to, uint deadline) external payable returns (uint[] memory amounts)',
'function getAmountsOut(uint amountIn, address[] memory path) public pure virtual override returns (uint[] memory amounts)'
], account);

const amountIn = 1
const fromTokenAddress = '0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c' //BNB
const toTokenAddress = '0xe9e7CEA3DedcA5984780Bafc599bD69ADd087D56' //BUSD

let amountOuts = await router.getAmountsOut(amountIn, [fromTokenAddress, toTokenAddress])

-> The first array element of amountOuts will be the amountIn you sent

EDIT: Decimal values can be send using the wei unit representation. Just multiply the value you want to send with 10 ** 18 like in the following example:

22.5 BNB -> 22.5 * 10 ** 18 = 22500000000000000000

There are lots of helpful libraries that can help you handling those numbers and providing functions for calculation. For example ethers.js includes such implementation which can be easily used just beware of the version you are using because the usage of BigNumbers in ethers.js is different in version.

There is a way to do it. You will have to create a domain that will allow HTTPS (Vercel is an example) host your MM code on the HTTPS site. On wix create a HTTPS iframe, and embed the site that host your MM code. I did it for a project that was on a Wix site. In this instance, I used Bubble's Web3/MM functionality and embedded it to this site: www.happylittleHairdos.com

Use https://metamask.github.io/metamask-deeplinks/ to deep link your site to auto open the MM app
