I am receiving an "Error validating ltik or IdToken: MISSING_VALIDATION_COOKIE" error when attempting to access Engageli

Overview

If you are attempting to access Engageli through your LMS platform (e.g. Canvas, Moodle, etc) and are receiving a "MISSING_VALIDATION_COOKIE" error, then the issue is likely due to your browser having 3rd party cookies disabled. The full error you may encounter is seen below:

{
  "status": 401,
  "error": "Unauthorized",
  "details": {
    "description": "Error validating ltik or IdToken",
    "message": "MISSING_VALIDATION_COOKIE"}
}

To resolve this, please configure your browser to allow usage of third-party cookies.

Enabling Third-Party Cookies for Chrome

Below are instructions on enabling third-party cookies in Chrome. You can also visit Google Chrome's article on this topic, found here. If you are using MS Edge or Brave, the instructions would be similar.

1. Within Chrome, click on the 3-dots menu at the top-right of the screen.
2. Select Settings.
3. In the Settings Search bar, type in cookies.
4. Look for the Third-party cookies section and select Allow third-party cookies.
   
5. You may need to restart your browser for the changes to take effect.

If the issue persists, it's possible that a Chrome extension is preventing third-party cookies from working properly. Try disabling all extensions temporarily to check if that resolves the problem. If it does, re-enable them one at a time to identify which extension is causing the conflict.

Enabling Third-Party Cookies for Incognito Mode

Lastly, Chrome tends to disable third-party cookies by default, when using Incognito mode. If you must use Incognito mode with Engageli, you can temporarily allow third-party cookies by doing the following:

1. Selecting the "site information" icon to the left of the address bar.
2. Select "Cookies and site data" from the menu.
3. Toggle the "Third-party cookies" switch to enable it.
