Lambda is not able to access API gateway Invoke URL - node.js

Question

I have written an AWS Lambda function in AWS account A and exposed one api in AWS account B. The api url looks like https://*******.execute-api.ap-south-1.amazonaws.com:443/abc.
Now, when I try to access this url through Lambda in AWS account A, I am getting forbidden exception. Also, I am able to access https://google.com from Lambda. The API exposed in AWS account B is working through Postman. Please suggest if I am missing something.
Also, Forbidden is not coming from the api if I hit the api from postman with wrong authorization token or no auth token.

UPDATE:
This is the issue:

NodeJs Code
const request = require("request");
request(authRequestBody, (error, response) => {
