AWS X-Ray NodeJs sdk in lambda, throws error No sub/segment specified. A sub/segment must be provided for manual mode

Question

I have the following lambda function.

import * as xray from 'aws-xray-sdk';

import * as http from 'http';
import * as https from 'https';

// This is my business logic
import {handler} from './handler';

xray.enableManualMode();
xray.capturePromise();

export async function myLambda(
  event: {
    traceId: string // from another service
    parentSegmentId: string // segment id of the service which generate this event
  },
  context: Context
) {
  const parentSegment = new xray.Segment(context.functionName, event.traceId, event.parentSegmentId);
  xray.setSegment(parentSegment);
  parentSegment.addMetadata('event', event);

  xray.captureHTTPsGlobal(http);
  xray.captureHTTPsGlobal(https);

  try {
    await handler(event);
    parentSegment.close();
  } catch (err) {
    parentSegment.addError(error);
    parentSegment.close();

    throw err;
  }
}

When I call my lambda function via SQS, I get the below-mentioned error (in my cloudwatch logs).

Error: No sub/segment specified. A sub/segment must be provided for manual mode. at Object.contextMissingLogError [as contextMissing] (/var/task/webpack:/home/ct/node_modules/aws-xray-sdk-core/lib/context_utils.js:26:1) at Object.resolveSegment (/var/task/webpack:/home/ct/node_modules/aws-xray-sdk-core/lib/context_utils.js:77:1) at captureOutgoingHTTPs (/var/task/webpack:/home/ct/node_modules/aws-xray-sdk-core/lib/patchers/http_p.js:66:1) at Object.captureHTTPsRequest [as request]

I'm currently using v2.4.0 of x-ray nodejs sdk.

Can anyone help me with this?
