v17development-flarum-seo failed to initialize (fireApplicationError.ts:11:10)
TypeError: F() is undefined

Index.ts:45

I am not sure what exactly causes this issue, as the other stacktrace belongs to the Flarum error handling source code. However, the extension seems to still load fine, despite the error message.
