Steps to Reproduce

• npm i request robots-parse
• Run the following code

const req = require('request');
req("https://optinmonster.com/robots.txt", (err, res, body) => {
if (err) {
   console.log("Robots Parser Error");
   console.error(err);
   return reply.code(404).send({
       error: "Couldn't find sitemap. Please provide sitemap URL",
    });
}

const { parser } = require("robots-parse");
const object = parser(body);
console.log(object);
console.log(object.sitemaps);
}
);

• Input the following URL in request - https://optinmonster.com/robots.txt

After doing these, I got the following error
