[Bug] Crash @kotlin.KotlinNullPointerException: at mozilla.components.service.fxa.manager.FxaAccountManager.postAuthenticated(FxaAccountManager.kt:36)

[bobintetley]

When I sign in to firefox and go through the pairing procedure, everything appears to work. I'm shown the success message on both phone and desktop browser. Once approval is given on both devices, approx 2 seconds later the app crashes. There is nothing in the logs via logcat. Let me know if there's any other debug information I can get to assist.

Device information

• Android device: OnePlus 5T
• Fenix version: 77.0.0-beta.2 Build #2015744451 42.0.1 5bf46033e GV: 77.0-20200526221856 AS: 0.58.2 Friday 6/5 @ 8:21 AM

I'm not seeing this signature at all when searching Sentry for FxaAccountManager.postAuthenticated. I checked all the active Fenix projects.

This is in a-c, not a-s.

The obvious thing that can NPE in that stacktrace (unfortunately line numbers are wrong) is fxaDeviceId = account.getCurrentDeviceId()!!.

Filed mozilla-mobile/android-components#7536 to track this.
