Error: invalid BigNumber value when calling contract but estimate gas works with the same parameters

Describe the Problem

When I call a contract with a Celo JRPC it fails saying invalid BigNumber and looks it complains about having an undefined value for gasLimit

I have tried with the BSC and it works, I have tried to add gasLimit as an override but it gives the same error

Code Snippet

const providerCelo = new ethers.providers.JsonRpcProvider('https://alfajores-forno.celo-testnet.org', 44787);

const walletCelo = new ethers.Wallet(walletCeloKey, providerCelo);
const contractCelo = new ethers.Contract(addressCelo, ABI, providerCelo);
const contractWithSignerCelo = contractCelo.connect(walletCelo);

//this works and gives me gas estimation
await contractWithSignerCelo.estimateGas.addVerifyAddress(req.body.address, req.body.isVerified)


//this fails when using Celo JRPC, for BSC it works
await contractWithSignerCelo.addVerifyAddress(req.body.address, req.body.isVerified)

Same error here using websocket provider

Code:

const buyToken = async(account, tokenContract, gasLimit, gasPrice) => {
  const buyAmount = 0.1
  const slippage = 0
  let amountOutMin = 0;
  const amountIn = ethers.utils.parseUnits(buyAmount.toString(), 'ether');
  if (parseInt(slippage) !== 0) {
  const amounts = await router(account).getAmountsOut(amountIn, [BNB_CONTRACT, tokenContract]);
  amountOutMin = amounts[1].sub(amounts[1].div(100).mul(`${slippage}`));
  }

  const tx = await router(account).swapExactETHForTokensSupportingFeeOnTransferTokens(
    amountOutMin,
    [BNB_CONTRACT, tokenContract],
    account.address,
    (Date.now() + 1000 * 60 * 10),
    {
        'value': amountIn,
        'gasLimit': gasLimit,
        'gasPrice': gasPrice,
    }
  );
  const receipt = await tx.wait();
  if (receipt && receipt.blockNumber && receipt.status === 1) { // 0 - failed, 1 - success
    console.log(`Transaction https://bscscan.com/tx/${receipt.transactionHash} mined, status success`);
  } else if (receipt && receipt.blockNumber && receipt.status === 0) {
    console.log(`Transaction https://bscscan.com/tx/${receipt.transactionHash} mined, status failed`);
  } else {
    console.log(`Transaction https://bscscan.com/tx/${receipt.transactionHash} not mined`);

You can not pass the decimal "131.424000001" as an integer.

I’m not sure which line is causing that error, but that’s what the error is saying. Check your stack trace to find the offending line. :)

[garciapd]

@ricmoo any hint about what could be happening to my example?

@ricmoo any hint?

[ricmoo]

You will need to subclass Provider and the Formatter to accept the alternate response. You can look at the BSC ancillary package to see how to make the sub-classes.

I’m working on v6 right now, and Celo will have its own ancillary package to resolve this. :)

[ricmoo]

Oh, the ancillary package for OkExchain is a better example, as their blocks differ more significantly.

Again, in v6, this is handled in the Network object, so it is much easier to extend and more flexible. :)

[nategraf]

This is a good solution to this issue for now. We are also looking into adding a gasLimit field to the RPC response to ensure that this can be resolved without having users need to apply a workaround. (For context, the field was removed from the block itself before mainnet launch because the gas limit is stored on a smart contract rather than in the block header. We now see that it should have been added to the RPC response, if not the RLP serialized form).

[piersy]

@ricmoo Would you have any idea about when you will be releasing v6 with support for Celo?
