the default value for uint variable is 10 now on function call, I want to change this value to 0

steps to reproduce:

  1. copy the following code to remix:

    contract test {
        uint128 public aPos=10;
        function updateQuota( uint128  _Quota){
            aPos = _Quota;
  2. Use the environment as a web3 provider (configure local ganache server with remix ID)

  3. Deploy contract.

  4. Call updateQuota function with parameter as 0

  5. Shows error as

"transact to test.updateQuota errored: base fee exceeds gas limit "


Question: how to assign zero value to uint variable when we work with the web3 provider (local ganache server)

  • This (annoying) problem has also been reported on GitHub (web3.js if I remember correctly). Aug 16, 2018 at 10:07
  • Surprisingly i'm facing exact same issue when following Pet Shop tutorial from Truffle. Have you managed to fix this? Long shot, but remember how? May 9, 2021 at 23:37

You most probably have assinged too little gas to the transaction. The Solidity code is fine (works as-expected with injected JS VM). Try using gasPrice: 8000000000 and gas: 4700000, that should run fine on ganache.

    i changes with this gas price and gas limit but still not working.. Aug 16, 2018 at 10:54
  • What values do you have for price + and block gas limit on the ganache gui? (i think the defaults are "6721975" for the maximum block gas and 20000000000 for the price) Aug 24, 2018 at 14:39
