Management API Explorer Page Crashes with "TypeError: o is undefined" Error

Problem statement

When attempting to set an access token on the Management API Explorer page, an error occurs with the message:

“TypeError: o is undefined”.


This error can occur if a browser extension is interfering with the page. For example, a Firefox Password Manager Addon has been responsible for this page crashing.


Try disabling browser addons/extensions and test setting a token for the page.
