I am using PDFTRON Webviewer to display pdf files in a modal view. My project is working properly in localhost. But it displays a blank modal page after it deployed in AWS amplify.

The folder structure is as mentioned in the pdftron documentation. During deployment I am getting a different index.html file as response. So, the pdftron webviewer is not getting rendered. Is this happening due to the optimized build.

I have attached my code, path directory image and my response during deployment for your reference.

Kindly help me with the above mentioned query. As this matter is urgent, I would appreciate a response as soon as possible.

import ReactPlayer from "react-player";
import * as React from "react";
import WebViewer from "@pdftron/webviewer";
import { Dialog } from "@mui/material";
import { makeStyles } from '@mui/styles'
import Loading from "./loading";

const useStyles = makeStyles(() => ({
  pdfStyle: {
    height: '90vh'
  videoStyle: {
    overflowY: "hidden"

export default function CustomModal(props) {
  const classes = useStyles()
  const viewer = React.useRef(null);
  const { fileUrl, type, toggleModal, filesActionList } = props;

  React.useEffect(() => {
    if (type && type === "application/pdf" && fileUrl!==null) {
        path: '/webviewer/lib',
        initialDoc: fileUrl,
        disabledElements: ["header", "toolsHeader"],
      }, viewer.current).then((instance) => {
        const { documentViewer } = instance.Core;
  }, [fileUrl, type])

  return (
      {(type && type === "link" && fileUrl) ? (
          height="calc(91vh - 100px)"
          : (type && type === "application/pdf" && fileUrl) ? (
            <div ref={viewer} className={classes.pdfStyle}></div>
            ) : (
              <Loading />
