I have a function which get a parameter as String and compare it like below.

function freezeAccount(string _value) onlyOwner public {     if (keccak256(_value) == keccak256("true")){ isFrozen = "true"; }     if (keccak256(_value) == keccak256("false")){ isFrozen = "false"; } }

Above is my smart contract code. I wanna use this my method using web3 so I’m trying to make transition by send() function like below.

export const setFreezeAccount = value => { console.log("setFreezeAccount :: value: ", value);   const str = value.toString();    myContract.methods   .freezeAccount(str)   .send({ from: TOKENOWNER })   .then(receipt => {     console.log("setFreezeAccount :: receipt: ", receipt);   })   .catch(err => {     console.log("setFreezeAccount :: err: ", err);   }); };

The freezeAccount() function is working well on Remix IDE but the Error: Invalid JSON RPC response: "" error returned When I execute the setFreezeAccount() function.
