Gas Limit error with `useWeb3Contract`

PatrickAlphaC · April 19, 2022, 12:41am

I’m working with react-moralis and have a runContractFunction:

    const { runContractFunction: buyItem, error: buyError } = useWeb3Contract({
        abi: nftMarketplaceAbi,
        contractAddress: nftMarketplaceAddress,
        functionName: "buyItem",
        msgValue: price,
        params: {
            nftAddress: nftAddress,
            tokenId: tokenId,
        },
    })

However, I’m getting an error:

Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ]

Is there a way to manually set gas?

I think it would be as easy as adding overrides right?

      break;
    default:
      throw new Error(`Unknown transfer type: "${type}"`);
  }
  const result = await transferOperation;
  return result;
}
static async executeFunction({
  contractAddress,
  abi,
  functionName,
  msgValue,
  params = {},
  overrides = {},
} = {}) {
  const contractOptions = {};
  const {

there isn’t a way now to set the gas in a parameter, usually you get that error when the transaction would generate an exception on execution

Dang. This would be a great improvement then.

I’ve worked with a number of transactions that have failed because they couldn’t estimate the gas limit, would love to see this overrides bit implemented.
