I'm working with the AdonisJS framework and have embedded the following two routers into it. The AdonisJS application generates a transaction object for swapping coins:

{
    to: '0x13f4EA83D0bd40E75C8222255bc855a974568Dd4', 
    value: 0, 
    data: '0x42712a670000000000000000000000000000000000000000000000000de0b6b3a76400000000000000000000000000000000000000000000000000000e54883aa311800000000000000000000000000000000000000000000000000000000000000000800000000000000000000000000fc0fbc1b573cf7c815906129c47fe4db515334000000000000000000000000000000000000000000000000000000000000000030000000000000000000000000e09fabb73bd3ade0a17ecc321fd13a19e81ce82000000000000000000000000bb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c000000000000000000000000bc7d6b50616989655afd682fb42743507003056d' // Ensure this is a valid hex string
}

to is the address of smart router on BSC (As mentioned here: https://developer.pancakeswap.finance/contracts/v3/addresses#smart-router), data is the execution of the contract's function.
I think data field is generated due to call the router contract (Pancake's router that I embedded). Subsequently, I tried to estimate the gas of that transaction using the following code:

const ethers = require('ethers');

// Connect to BSC node (you can use a public RPC or your own)
const provider = new ethers.providers.JsonRpcProvider('https://bsc-dataseed.binance.org/');

// Replace with your private key
const privateKey = 'fe78e112e8a94f339cf7669e6b83322365fd2e2ea71327404509fc5e3484693e';
const wallet = new ethers.Wallet(privateKey, provider);

async function estimateGas(transaction) {
    try {
        // Get current gas price
        const gasPrice = await provider.getGasPrice();
        console.log(`Current Gas Price: ${ethers.utils.formatUnits(gasPrice, 'gwei')} Gwei`);

        // Estimate gas limit for the transaction
        const gasLimit = await provider.estimateGas(transaction);
        console.log(`Estimated Gas Limit: ${gasLimit.toString()}`);

        // Calculate total transaction fee in BNB
        const transactionFee = gasPrice.mul(gasLimit);
        console.log(`Transaction Fee in Wei: ${transactionFee.toString()}`);
        console.log(`Transaction Fee in BNB: ${ethers.utils.formatEther(transactionFee)} BNB`);
    } catch (error) {
        console.error('Error estimating gas:', error);
    }
}

// Example transaction object (for sending BNB)
const transactionObject = {
    to: '0x13f4EA83D0bd40E75C8222255bc855a974568Dd4', // Replace with recipient address
    value: 0, // Amount of BNB to send
    data: '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' // Ensure this is a valid hex string
};

// Check if data is valid
if (!/^0x[0-9A-Fa-f]*$/.test(transactionObject.data)) {
    throw new Error('Invalid hex string for data');
}

estimateGas(transactionObject);

That is using the same transaction as input for estimateGas() function. But this error thrown:

    requestMethod: 'POST',
    url: 'https://bsc-dataseed.binance.org/'
  }
}

I tried that for Ethereum mainnet and the same error thrown!
As I researched, method provider.estimateGas() can't calculate the gas, because the transaction (call contract function) is too complex. I don't know why it is complex, that is just a guess!

What is the problem? Where did I make a mistake and how can I solve it?
