Contract response varies based on tx from value

[chaitanyapotti]

Description

Calling balances method in this contract
from an address which is an input, gives garbage results

Expected behavior

Should return correct wei balance

Actual behavior

gives garbage value

Steps to reproduce the behavior

const ABI = [{"constant":true,"inputs":[{"name":"user","type":"address"},{"name":"token","type":"address"}],"name":"tokenBalance","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"users","type":"address[]"},{"name":"tokens","type":"address[]"}],"name":"balances","outputs":[{"name":"","type":"uint256[]"}],"payable":false,"stateMutability":"view","type":"function"},{"payable":true,"stateMutability":"payable","type":"fallback"}]

const deployedContractAddress = '0xb1F8e55c7f64D203C1400B9D8555d050F94aDF39'
const addresses = ['0x6911207bb1B683014248E535889e79E648684b2B']
const ethContract = new web3.eth.Contract(ABI, deployedContractAddress)
const zeroAddress = [ZERO_ADDRESS]
ethContract.methods.balances(addresses, zeroAddress).call({ from: addresses[0] }, (error, result) => {
      if (error) {
        console.log(error)
      }
      addresses.forEach((address, index) => {
        const balance = result[index]
        console.log(balance)
      })
    })

Although, calling the same method using a different `from` address than the one in the `addresses` variable, gives the right results.

Thanks for opening this issue! Could you please add the returned values from this contract call?

[chaitanyapotti]

@nivida Here is the requested information

result: ["115792089237316195423570985008687907853269984665631340667420729232106129639935"]

whereas the correct answer should be

result: ["98486156000000000"] (units: wei)

[nivida]

Thanks for providing the missing information. We will test and probably fix it asap.
