Firebase Function malfunctioning with Hindi characters

Question

Firebase function is calling this Hindi API for dialogflow action. The firebase function is sending Error in API call, however it works perfectly when tested with english API, but that time my query text was also in English. The expected output is, it plays verses from Quran.

I think the problem is with query Text. It needs to have utf-8 encoding or something like that maybe? The firebase function is as following:

const functions = require('firebase-functions');
var request1 = require('request');

exports.webhook = functions.https.onRequest((request, response) => {
   console.log("request.body.result.parameters: ", request.body.queryResult.parameters);
   let params = request.body.queryResult.parameters;

   if (request.body.queryResult.intent.displayName === "verseByVerse") {
      var options = {
         url: `https://theislam360.me/api/find/hindi/${params.any}`,
         json: true
      }
      request1(options, function (error, res, body) {
         if (error) response.send({ fulfillmentText: "error in API call" });
         else {
            var audio ="";
            var length = Object.keys(body).length;
            var surah_id = [];
            var ayat_no = [];
            for (i = 1; i <= length; i++) {
               surah_id.push(body[`result_${i}`].Surah_No);
               ayat_no.push(body[`result_${i}`].Ayat_No);
               if ((surah_id[i-1]<10) && (ayat_no[i-1]<10)){
                  audio = audio + 
               `Surah Number ${surah_id[i-1]}, Ayat Number ${ayat_no[i-1]}<audio src='https://theislam360.me/api/play/versebyverse/00${surah_id[i-1]}00${ayat_no[i-1]}.mp3'></audio>`;   
               }
               else if ((surah_id[i-1]<10) && (ayat_no[i-1]>9) && (ayat_no[i-1]<100)){

You will get Request path contains unescaped character ERROR so you need encodeURI

var request1 = require('request');
var options = {
    url: encodeURI(`https://theislam360.me/api/find/hindi/आदमी`),
    json: true
 }
 request1(options, function (error, res, body) {
     console.log(error);
     console.log(body);
 })
