No value provided for input HTTP label: FunctionName - Openzeppelin Defender Actions Error

:computer: Environment
Working on defender monitor and actions, for automatic pause


  1. I am trying to run openzeppelin defender actions, but whenever I try to run,

const pauseTx = await contract.populateTransaction.pause();


// Send the transaction

const txResponse = await signer.sendTransaction({
to: safeAddress,
data: txData,

I am getting error -
No value provided for input HTTP label: FunctionName

  1. Also the dependencies are depreceated for - safe-sdk

:1234: Code to reproduce
Below is part of a code -

const { DefenderRelaySigner, DefenderRelayProvider } = require('defender-relay-client/lib/ethers');
const { ethers } = require('ethers');

exports.handler = async function(event) {
console.log("Received event:", JSON.stringify(event, null, 2));

// Initialize provider and signer
const provider = new DefenderRelayProvider(event);
const signer = new DefenderRelaySigner(event, provider, { speed: 'fast' });

// Define contract and ABI
const contractAddress = '0x43636F829952e21673b6Ace16d0771f1DAbBb008';
const ABI = ["function pause() external"];
const contract = new ethers.Contract(contractAddress, ABI, signer);

console.log("Before Populate");

// Ensure the method exists before calling populateTransaction
if (!contract.populateTransaction.pause) {
  throw new Error("The contract does not have a method called 'pause'.");

// Populate the transaction
const pauseTx = await contract.populateTransaction.pause(); --> Error Here

console.log(`Transaction executed successfully with hash: ${txResponse.hash}`);
