nodeError(desc: "intrinsic gas too low")

[AlleniCode]

I'm using Uniswap and WalletConnect to send transaction:

I made a transaction from json:

faced the same issue, I believe there is a bug in web3+options.swift

at the beginning of

public static func fromJSON(_ json: [String: Any]) -> TransactionOptions? {

there should be

 if let gas = json["gas"] as? String, let gasBiguint = BigUInt(gas.stripHexPrefix().lowercased(), radix: 16) {
            options.gasLimit = .manual(gasBiguint)

now it is set as limited, which is later replaced by default 21000...
