How to call a payable function in ethers, which takes 0 input and payable bnb?

Question

I have wrote it like this but it is always throwing error that inputAmount is not in range but it is in range,

const transaction = await preSaleContract.buyTokens({value: inputAmount, from: userAddress}) await transaction.wait(); and like this also

const transaction = await preSaleContract.buyTokens().send({value: inputAmount, from: userAddress});

Answer 1

Try parsing your input amount.

let tx = await connectedContract.YOUR_PAYABLE_FUNCTION(ALL, OTHER, PARAMETERS, {value: ethers.utils.parseEther(ETH_VALUE_AS_STRING)});

In Your case,

const transaction = await preSaleContract.buyTokens({value: ethers.utils.parseEther(inputAmount), from: userAddress})
