What is the function of Zotero.Schema.schemeUpdatePromise

[Soham S]

I have a third-party script which has `await Zotero.Schema.schemeUpdatePromise`

What is the functionality of the above call?

Roughly, that promise clears when Zotero's internal API is ready to use. The database will have been loaded and migrated if necessary, the path to the data files is known, etc. You can do some things before this point, and it takes at least a few seconds to clear after start, but anything you do before that is prone to race conditions and other hard to debug errors in my experience.
