Error: fractional component exceeds decimals

[ilkinm03]

Here's my code

async function main() {
    await getWeth()

    const { deployer } = await getNamedAccounts()
    const signer = await ethers.getSigner(deployer)
    const lendingPool = await getLendingPool(signer)
    console.log(`Lending pool address: ${lendingPool.address}`)

    const wethTokenAddress = "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"
    await approveERC20(wethTokenAddress, lendingPool.address, AMOUNT, signer)
    console.log("Depositing...")
    await lendingPool.supply(wethTokenAddress, AMOUNT, deployer, 0)
    console.log("Deposited!")

    let { totalDebtBase, availableBorrowsBase } = await getBorrowUserData(
        lendingPool,
        deployer
    )
    const daiPrice = await getDaiPrice()
    const amountDaiToBorrow =
        availableBorrowsBase.toString() * 0.95 * (1 / daiPrice.toNumber())
    console.log(`You can borrow ${amountDaiToBorrow} DAI`)
    const amountDaiToBorrowWei = ethers.utils.parseEther(
        amountDaiToBorrow.toString()
    )
    const daiTokenAddress = "0x6B175474E89094C44Da98b954EedeAC495271d0F"
    await borrowDai(
        daiTokenAddress,
        lendingPool,
        amountDaiToBorrowWei,
        deployer
    )
    await getBorrowUserData(lendingPool, deployer)
    // ....
}

The error occurs on the where I'm defining amountDaiToBorrowWei function with calling parseEther method
The full logs are as below
