Would crash when trying to parse my abi data

[PandaraWen]

I try to use my abi data to create a contract (as shown at the end), but always crash at a same place.

I just simply read json data from my .json file and than parsed it as a string:

self.web3 = Web3.newWeb3(URL(string: "http://localhost:8545")!)!

// ABI
guard let path = Bundle.main.path(forResource: "abi", ofType: "json"),
    let abiString = try? String(contentsOf: URL(fileURLWithPath: path)) else {
    fatalError("Can not get abi data")
}

// Contract
self.contract = self.web3.contract(abiString, at: EthereumAddress(self.contractAddress))!

When I run my program, it would crash at the last line in code snap above, giving an error in console:

parameterTypeInvalid

Am I missing something?

The abi data I used:

Hello @PandaraWen

Thank you for a valuable feedback, it was indeed a bug with "bytes32[]" like parameters parsing. Pushed a fix in 0.2.12.

Sincerely, Alexander

Oh thanks for your rapidly response, I would test again later on, and close this issue if everything goes well
