API docs: LSIF: prevent `null` lists in GraphQL responses
Created by: slimsag
Prior to this change, children and tag arrays could sometimes be null
in our GraphQL
JSON response data. This was sometimes incorrect (in the case of tags), and other times
just annoying to deal with. This change makes us do our best to prevent null
lists
from appearing in our data, preventing a myriad of bugs.
