Thanks @vinothkannans for getting back and for pointing us to @sam’s comment. After following this to [JavaScript not loading on certain pages](https://meta.discourse.org/t/javascript-not-loading-on-certain-pages/92297) and drilling down a bit further we would like to share our findings.

While the origin of this pretty much void object pretending to be a real Discourse instance

```plaintext
const Discourse = {
  SiteSettings: {}
}

```

is yet unknown, it will easily sneak through some safeguards the Discourse plugin loader had put into place, so

> if ('Discourse' in window) { 
> Discourse._registerPluginCode('0.8', function (api) {
> // [...]
> }
> }

would obviously be completely clueless about this and will just attempt to run the plugin registration right away as if nothing happened, ultimately croaking there.
