NullPointerException in com.google.firebase.database

[Sulabh Puri]

Getting this crash on crashlytics for a very few number of users.

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.String.toLowerCase(java.util.Locale)' on a null object reference

       at com.google.firebase.database.obfuscated.zzdq.zza(SourceFile:5111)

       at com.google.firebase.database.obfuscated.zzdq$2.run(SourceFile:143)

       at java.lang.Thread.run(Thread.java:818)

Not able to reproduce it locally. Any clues on how to resolve or reproduce it.

Thank in advance.

I received the same warning about a "Fatal issue" yesterday. It is for an app that I haven't touched in quite a while, and which isn't installed by too many users. I already wondered about that, but if others are seeing the same, it might not be an issue with our code at all.

Here's what I got:

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.String.toLowerCase(java.util.Locale)' on a null object reference

Hello,

I also got the same report from Crashlytics, I never managed to reproduce it locally.

Here is a snapshot from the Firebase Crashlytics:

There is a big chance that this is the issue:

According to the post, there is rooted Nexus 5X device that runs automated tests and crashes..
