Unhandled Promise rejection: No Services matching UUID 0000ffe0-0000-1000-8000-00805f9b34fb found in Device.

I am trying to integrate this library to connect a weight scale with angular electron project and facing an error.

Dependencies:

"@angular-devkit/build-angular": "~12.2.18",
"@angular/cli": "^12.2.18",
"@angular/compiler-cli": "~12.2.0",
"@abandonware/noble": "^1.9.2-23",

node version - 14.15.0
npm version - 6.14.8

I think the problem is in the last line of the below code because it is getting service but not characteristics

module.exports = {
init: function (event) {
noble.on('stateChange', (state) => {
if (state === 'poweredOn') {
console.log('Scanning');
noble.startScanning([ECHO_SERVICE_UUID], false);
} else {
noble.stopScanning();
}
});

noble.on('discover', (peripheral) => {
  // connect to the first peripheral that is scanned
  noble.stopScanning();
  const name = peripheral.advertisement.localName;
  console.log(`Connecting to '${name}' ${peripheral.id}`);
  connectAndSetUp(peripheral);
});

}
}

function connectAndSetUp(peripheral) {
peripheral.connect((error) => {
if (error) {
console.error(error);
return;
}

console.log('Connected to', peripheral.id);

// specify the services and characteristics to discover
const serviceUUIDs = [ECHO_SERVICE_UUID];
const characteristicUUIDs = [ECHO_CHARACTERISTIC_UUID];

console.log(serviceUUIDs, characteristicUUIDs);

peripheral.discoverAllServicesAndCharacteristics(
  onAllServicesAndCharacteristicsDiscovered
);
