Get Error message of require statement

[nobita851]

Assume contractInstance.methodName(methodArgs) fails due to a require statement. What I want is the error message of that require statement.

I want the status message of the following image.

Error received:

Any help is appreciated.

If the node includes the revert reason, ethers.js should display that in the error. You can try the following

const provider = new StaticJsonRpcProvider('https://data-seed-prebsc-1-s1.binance.org:8545/')
const tx = await provider.getTransaction('0x42bb7f43c4258ebd805d14367bfbc7b8214e2ff752b0a8bf57816d0eb414a0fd')
const result = await provider.call(tx, tx.blockNumber)
const iface = new Interface(['function Error(string)']);
const decodedError = iface.decodeFunctionData(result.slice(0,10), result)

Hi @zemse , Thanks for helping

Can you help me what to pass in new Interface([])
My method signature function getTokens(uint256 _index) public payable nonReentrant returns (bool success)

Currently I am getting:

Error: no matching function (argument="sighash", value="0x08c379a0", code=INVALID_ARGUMENT, version=abi/5.5.0)
