Lifecycle of validateAppId

Following up on this thread, when does validateAppId run? In server initialization or in every login request?

@Moumouls any help here since you are refactoring the login part of the code in Parse?

It runs every login: parse-server/index.js at 4c29d4d23b67e4abaf25803fe71cae47ce1b5957 · parse-community/parse-server · GitHub
