Value not in range: 32 #59

YDJSZY · 2019-09-06T06:55:06Z

When I call your contract dart in example and it happend a error: Value not in range: 32
this is my code:

try {
      final balance = await web3client.call(
      contract: contract, function: balanceFunction, params: [ownAddress]);
      print('We have ${balance.first} MetaCoins');
    } catch (error) {
      print(error);
    }

simolus3 · 2019-09-06T07:11:14Z

Can you try replacing the catch statement with

catch (error, trace) {
  print(error);
  print(trace);
}

And give me the output of the stacktrace? Thanks!

Thank you for the report. This seems similar to #47 (comment), so a bit more information would be helpful to find the cause

are you running the latest flutter version? We had a very similar bug that was actually caused by Flutter
does is only happen for release builds or for debug builds as well?
(optional) To make debugging easier for me, can you attach a logger to the HttpClient you pass to the Web3Client constructor? The comment linked above contains information on how to do that. This lets me inspect the raw data returned from the contract. Be aware that these calls could contain potentially sensitive information (your Ethereum node, address, contract address, payload you send to the contract). You can strip out some information if you like or, if you don't want to post these details publicly, e-mail them to me at [email protected].

YDJSZY · 2019-09-06T08:07:09Z

Thanks for your detail reply!
I change your abi.json to https://github.com/danfinlay/human-standard-token-abi, and it work! it return my erc20 token balance successfully.
my contract address is 0x01e5ad4f8fb032f80ec0e3de7f4221b46f81d4c9 and my eth address is
0x6c0d0870ec3af6411332f9524640e7f781941e0e.
I used your abi.json, your privateKey and contract before, but it showed error "Value not in range: 32"

simolus3 · 2019-09-06T08:53:28Z

Oh interesting! The abi from the repo you linked doesn't define a "getBalance" function, it has a "balanceOf" function instead. They both declare the same return types though, so I'm surprised that didn't work. I'll take a more detailed look later.

AyushBherwani1998 · 2020-03-06T02:44:30Z

Hey @simolus3 , I'm still getting this error. I checked, the function is available in the abi.json and also on the smart contract.

await ethClient.call(
        contract: contract,
        function: checkOrgan,
        params: [user.bloodGroup,model.organDescription]).catchError((error,trace){
          Logger(printer: PrettyPrinter()).e("Error: $error");
    })

@simolus3 Any updates on the issue?

simolus3 · 2020-03-10T17:48:53Z

Sorry for the delay - unfortunately I couldn't find a bug in web3dart here. We have tests to verify that booleans are encoded and decoded correctly.

Can you try attaching a logger to the http client (for instance like this) and post what the eth_call request returns? If you're uncomfortable posting that publicly you can also send it to me at [email protected].

i got this error today with a function in the aave contract with no boolean involved only uint256 but the bug is not always here will investigate more if it reproduce

in lib/src/crypto/formatting.dart when i print bytes.toList() i got this :

[8, 195, 121, 160, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 32, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 30, 83, 97, 102, 101, 77, 97, 116, 104, 58, 32, 115, 117, 98, 116, 114, 97, 99, 116, 105, 111, 110, 32, 111, 118, 101, 114, 102, 108, 111, 119, 0, 0]

so here we have a 100 element List but then in lib/src/contracts/abi/integers.dart
if here i print the offset it got 96 with sizeUnitBytes at 32 this lead us to 128 which in above the 100 element array which lead to the error.

kevin-sakemaer · 2020-03-12T15:46:21Z

i call the method getUserAccountData there is the return type here https://developers.aave.com/#lendingpool

Notice that not all call fail but only some of them which render the task of debugging it pretty complicated.

simolus3 · 2020-03-13T21:49:24Z

i call the method getUserAccountData there is the return type here https://developers.aave.com/#lendingpool

Interesting. That method returns 8 uint256 values, so I'd also expect 256 bytes of payload data - it weird that we only get 100.
I think the decoding failing here is correct - the 100 byte list just can't be decoded as 8 values of that type. It's worth investigating why we don't get a complete result though - what node are you connecting to? Or do you have a way for me to reproduce this?

kevin-sakemaer · 2020-03-13T21:54:38Z

i'm on mainnet and i can provide you an address that fail everytime.
0x338a370bd32b454345182365b380664cbe660998
I will open source my aave sdk soon (next week) so it will be easier to test everything.

Thanks a lot @AyushBherwani1998! I can reproduce this problem locally. I think this might be an infura bug: INFURA/infura#157
It's pretty weird that we get this error consistently though, and not just occasionally. It looks infura returns 0x instead of throwing an error when calling an invalid address - are you sure 0xdce881db68e093637378083611367dac5bb7ce3b is correct? I also noticed you're passing O+ (the letter) instead of 0+ (the number) as bloodGroup, but I guess that shouldn't matter for this error.

This sounds weird. The address is correct. I'm able to do transactions but not able to call functions.

ltfschoen · 2020-06-23T15:55:02Z

I had the same error.
It was because although I was using the correct abiCode that corresponded to the latest version of the smart contract I was calling, I had provided a contractAddr that corresponded to a different smart contract all together. So I just provided the correct smart contract address to contractAddr to fix the issue. See code snippet below:

final contract = DeployedContract(
        ContractAbi.fromJson(abiCode, 'DataHighwayMXCMiningToken'),
        contractAddr);
final getStuffFunction = contract.function('getStuff');
await client.call(
        contract: contract,
        function: getStuffFunction,
        params: [ownAddress]);

This happens if the RPC endpoint replies with 0x, an invalid response that cannot be parsed into the return values indicated in the ABI. The question is why that happens. If anyone has a contract with sources on a public net (can be a testnet) that reproduces this, I'd love to take a look.

I've found the source of the error and it was related to an improper use of the Convert dart package (for decoding/encoding the json abi) rather than an error brought on by Web3dart or the implementation thereof. I adjusted this and the code worked wonderfully. Thanks as well to simolus3 for reaching out.

Had this issue when I was trying to use a contract that was not deployed on the network.

Maybe that could help.

RPC endpoint replies with 0x, an invalid response that cannot be parsed into the return values indicated in the ABI.

you can view the contract source at this address on the ropsten testnet:
0xA8c53a4D9e1D47A0E2ECCA6bd0334445541ce88F

I've found the source of the error and it was related to an improper use of the Convert dart package (for decoding/encoding the json abi) rather than an error brought on by Web3dart or the implementation thereof. I adjusted this and the code worked wonderfully. Thanks as well to simolus3 for reaching out.

@John1Fazio can you please share the code that you adjusted?

Hey @simolus3 Is there any update on the issue? I am still facing it

It's been a while since this issue, so I'm foggy on the details. Following this code, you should be able to connect to Web3Dart and call functions on your smart contract. The private key and my infura key are omitted for obvious reasons.

Let me know if this is even helpful. If not, I may be able to share more code.

`import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:http/http.dart';
import 'package:web3dart/web3dart.dart';

class MainModel {
  Client? httpClient;
  Web3Client? ethClient;
  String apiUrl =
      ''; //RPC url goes here

  MainModel() {
    initiateSetup();
    print("connected to the blockchain at: $apiUrl");
  }

  Future<void> initiateSetup() async {
    httpClient = Client();
    ethClient = Web3Client(apiUrl, httpClient!);

    await getCredentials();
    await getDeployedContract();
    await getContractFunctions();
  }

  String privateKey =
      '';
      //privatekey goes here
  Credentials? credentials;
  EthereumAddress? myAddress;

  Future<void> getCredentials() async {
    final credentials = EthPrivateKey.fromHex(privateKey);
    myAddress = await credentials.extractAddress();
  }

  EthereumAddress? contractAddress;

  Future<void> getDeployedContract() async {

    contractAddress =
        EthereumAddress.fromHex('0xBDF17b9291673964BC410324169780C024608C8d');
  }

  DeployedContract? contract;
  ContractFunction? mint,
      burn,
      tokenURI,
      approve,
      transferFrom,
      balanceOf,
      getApproved,
      isApprovedForAll,
      name,
      symbol,
      ownerOf,
      supportsInterface;

  Future<void> getContractFunctions() async {
    String abi = await rootBundle.loadString('src/artifacts/NFT.json');
    contract =
        DeployedContract(ContractAbi.fromJson(abi, "NFT"), contractAddress!);
    print(contractAddress);
    //TRANSACTIONS
    mint = contract!.function('mint');
    burn = contract!.function('burn');
    approve = contract!.function('approve');
    transferFrom = contract!.function('transferFrom');
    //CALLS
    balanceOf = contract!.function('balanceOf');
    getApproved = contract!.function('getApproved');
    isApprovedForAll = contract!.function('isApprovedForAll');
    name = contract!.function('name');
    symbol = contract!.function('symbol');
    ownerOf = contract!.function('ownerOf');
    tokenURI = contract!.function('tokenURI');
    supportsInterface = contract!.function('supportsInterface');
  }


  Future<List<dynamic>> readContract(
    ContractFunction functionName,
    List<dynamic> functionArgs,
  ) async {
    try {
      var queryResult = await ethClient!.call(
        contract: contract!,
        function: functionName,
        params: functionArgs,
      );
      return queryResult;
    } catch (error, trace) {
      print(error);
      print(trace);
      throw error;
    }
  }


  Future<void> writeContract(
    ContractFunction functionName,
    List<dynamic> functionArgs,
  ) async {
    await ethClient!.sendTransaction(
        credentials!,
        Transaction.callContract(
          contract: contract!,
          function: functionName,
          parameters: functionArgs,

        chainId: 3);
  }

I experienced this but managed to solve it by changing to Injected Web3 Environment..
Am using the Ropsten Test Network
