I am very new to Ethereum smart contract solidity programming. Currently, I have been facing this issue when I try to pass a variable from my Node.js servlet to the smart contract I deployed using Truffle Suite, specifically with accounts provided by Ganache.

Following is the JavaScript I used to connect and call the smart contract method:

if (this.state.contract) {
                .send({from: this.state.account, gas: 210000, gasPrice: 50000}, function (err, res) {
                    if (err) {
                        console.log("Error", err)

Following is the Solidity code in smart contract:

function searchKeyword (string memory searchToken) public {
        searchWord = searchToken;

Whenever I call the function and pass searchToken , the following error pops up. I have tried setting the gas and gasPrice over, within, below the gasLimit of my MetaMask wallet but I am still getting errors like Exceeds block gas limit. I have tried without setting the gas and gasPrice but I am still getting the similar issue.

Any genius please help me this noob beginner who trying so hard to debug just a small little function. Thank you guys in advance :D

  • Did you try using more gas? I'd start with 5M gas, string are expensive.
