Invalid token specified: Cannot read property 'replace' of undefined

I get Invalid token specified: Cannot read property ‘replace’ of undefined:

Object.<anonymous> ../node_modules/jwt-decode/lib/index.js 9:0
Showing original source content from sourcemap
'use strict';
 var base64_url_decode = require('./base64_url_decode');
 function InvalidTokenError(message) {
  this.message = message;
}
 InvalidTokenError.prototype = new Error();
InvalidTokenError.prototype.name = 'InvalidTokenError';
 
module.exports = function(token, options) {
    if (typeof token !== 'string') {
      throw new InvalidTokenError('Invalid token specified');
    }

Can i get any help ASAP please?!

I had same problem as well, If you are login to the App and you did play with token in backend(postman). then token mismatch might happen so you take recent token from postman and add it to the localstorage in the browser, which was in undefined.

In my case, I’m attempting to protect the client-side app against “corrupt” cookies (tokens that aren’t in JWT format) in the event a user messes with their cookies. In the moment I’m decoding, if the token can’t be parsed, the error thrown breaks the app, despite my attempt to catch.

export const isAccessTokenExpired = (): boolean => {
  if (!isAccessTokenSet()) {
    // if it doesn't exist, we'll also consider it expired
    return true;
  }

  // ensure it's actually JWT format
  try {
    jwt_decode(getAccessToken());
  } catch (error) {
    console.log('👾 invalid token format', error);
    return true;
  }

  const token = jwt_decode(getAccessToken());
  const { exp } = token;
  return Math.round(Date.now() / 1000) >= exp ? true : false;
};

Upon attempting to decode a non-JWT format value, the catch triggers, but the error still shows as Uncaught and breaks runtime:

👾 invalid token format InvalidTokenError {message: "Invalid token specified: Cannot read property 'replace' of undefined"}

Uncaught InvalidTokenError {message: "Invalid token specified: Cannot read property 'replace' of undefined"}
message: "Invalid token specified: Cannot read property 'replace' of undefined"
