ethers.js throws invalid BigNumber error from estimateGas

[yuetloo]

The following error was received when estimating gas on a contract function that reverts.

This error seems to only happen if the walletConnect web3-provider was used. I tested with the Infura and etherscan providers, they both throw with the revert reason as expected.

 invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.0.13)

The error was thrown in the return statement in the following code. The BigNumber.from() didn't expect an undefined returned from the estimateGas().

// base-provider.ts
async estimateGas(transaction: Deferrable<TransactionRequest>): Promise<BigNumber> {
        await this.getNetwork();
        const params = await resolveProperties({
            transaction: this._getTransactionRequest(transaction)
        });
        return BigNumber.from(await this.perform("estimateGas", params));
    }

Thanks! I’ll go through the provider methods a bit and make sure better errors are bubbled up. :)

I'm also facing this issue when trying to perform payable Contract method and specifying amount i'm want to send.

You can test deployUserWallet method from etherscan contract writeContract

factory_address: 0xdDB10cFC3cea471708B1647415F71BCeA9f96145
w2w_address: 0x41b2E493D3698F6D23466b46266BBEAd6a07Bf56

Works when not specified amount

Error when amount passed to overrides

is it fixed somehow ?

@edward-arinin-web-dev , this issue was about the original error being swallowed instead of bubbling up and it's not fixed yet.

For your case, were you using the same signer to call createUserWallet()? The contract reverts if the same signer was used to createUserWallet(), regardless of whether amount is passed in or not.

This should be fixed in 5.0.31. Try it out and let me know! :)

Closing this now, but if you still have issues, please feel free to re-open.

Thanks! :)

Hi I am getting the same error from ethers abi. Here is the error stack from node --trace-warnings

My code is:

const uniswap = new ethers.Contract(
        "0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D", // Router V2
        [
            "function swapExactETHForTokens(uint amountOutMin, address[] calldata path, address to, uint deadline) external payable returns (uint[] memory amounts)"
        ],
        account
    );
    const to = "0x7Df54B22Bf8B7eB6b19B667aABe977B2dfD1c5db";
    const path = [weth.address, uni.address];
    const tx = await uniswap.swapExactETHForTokens(. // <-------------- Error comming from this
        1,
        path,
        to,
        deadline,
        {value, gasPrice: ethers.utils.parseUnits('20', 'gwei')}
    );

Could anyone help on this?

A bit more info:

• the path is resolved into:

[
  '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2',
  '0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984'
]

• the swapExactETHForTokens is from uniswap v2 https://uniswap.org/docs/v2/smart-contracts/router02/#swapexactethfortokens

[ricmoo]

Can you please add this console.log directly above the call:

console.log({ path, to, deadline, value });

My first guess is that your value is an array; perhaps you have a variable with the same name shadowing the local variable.
