Error: Failed to fetch gas estimate on intermediate call

[barrasso]

Hi All, I am having some trouble calling a method on the ENS registrar contract. Some methods work fine, while others give me a gas estimation error.

For example, I am able to call startAuction with no problems like so:

let parameters = ["0x\(name.labelHash!)"] as [AnyObject]
DispatchQueue.global().async {
    let gasPriceResult = Keys.shared.web3.eth.getGasPrice()
    guard case .success(let gasPrice) = gasPriceResult else {return}
    var options = Web3Options.defaultOptions()
    options.gasPrice = gasPrice
    options.gasLimit = BigUInt(200000)
    options.from = Keys.shared.manager?.addresses?.first!
    DispatchQueue.global().async {
        let contract = Keys.shared.web3.contract(Web3.Utils.registrarABI, at: ENSRegistrar.registrarContract, abiVersion: 2)!
        let intermediate = contract.method("startAuction", parameters: parameters, options: options)
        guard let res = intermediate?.send(password: "PASSWORD") else {return}
        switch res {
        case .success(let res):
            completion(true, nil)
        case .failure(let error):
            completion(false, error)
        }
    }
}

Starting the auction works fine and the tx goes through: https://ropsten.etherscan.io/tx/0x59ad6cfa53985301ecdf6c07df20b02e55aa31965a45e14e0b2f6b3ec5e85823

However, when I try to call newBid in the same manner, I get a gas estimation error.

This is the error I am getting. It happens at the case .failure line:

failure res: .failure(processingError(desc: "Failed to fetch gas estimate"))

Here is my code calling newBid:

let parameters = ["0x\(sealedBid!)"] as [AnyObject]
DispatchQueue.global().async {
    let gasPriceResult = Keys.shared.web3.eth.getGasPrice()
    guard case .success(let gasPrice) = gasPriceResult else {return}
    var options = Web3Options.defaultOptions()
    options.gasPrice = gasPrice
    options.gasLimit = BigUInt(200000)
    options.from = Keys.shared.manager?.addresses?.first!
    let contract = Keys.shared.web3.contract(Web3.Utils.registrarABI, at: ENSRegistrar.registrarContract, abiVersion: 2)!
    let intermediate = contract.method("newBid", parameters: parameters, options: options)
    DispatchQueue.global().async {
        guard let res = intermediate?.send(password: "PASSWORD") else {return}
        switch res {
        case .success(_):
            completion(true, nil)
        case .failure(let error):
            // this is where I'm getting a gas estimation error
            print("failure res: \(res)")
            completion(false, error)
        }
}

I am using the following contract on Ropsten: https://ropsten.etherscan.io/address/0xc19fd9004b5c9789391679de6d766b981db94610#code

I'm not sure why one function is working while the other is throwing gas estimation errors. Is there a way to NOT use the gas estimator? Thanks!

Found the error.

Must set options.value = BID_VALUE+MASKED_VALUE, when calling the newBid function.
