Firebase-auth与Facebook出错

Question

Firebase auth with Facebook just stopped working on all our Polymer websites. One of them where updated 19th of march and has been working until yesterday/this afternoon (2017-03-27).

I get the following error message in chrome:

firebase-auth.js:32

"{"error":{"errors":[{"domain":"global","reason":"invalid","message":"A system error has occurred"}],"code":400,"message":"A system error has occurred"}}

Answer 1

Firebase Authentication is having problems right now. Look at the Firebase Status Dashboard here:

Answer 2

Graph API v2.2 has reached the end of its 2-year lifetime on 27 March, 2017, so this might be connected. You should check your library and possible updates. See this chart of deprecation dates , which lists v2.2 as available until March 25, 2017.
