nullPointerException in com.google.android.gms.internal.config.zzal

[Sulabh Puri]

we getting these crashes on crashlytics, not able to reproduce on our end.

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'long com.google.android.gms.internal.config.j.b()' on a null object reference
       at com.google.android.gms.internal.config.zzan.run(Unknown Source)
       at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:234)
       at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113)
       at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588)
       at java.lang.Thread.run(Thread.java:818)

below is our Proguard mapping-

com.google.android.gms.internal.config.zzal -> com.google.android.gms.internal.config.j:
    int zzaq -> a
    long zzar -> b
    void <init>(int,long) -> <init>
    int getResourceId() -> a
    long zzo() -> b

and we use these firebase dependencies:

    implementation 'com.google.firebase:firebase-ads:16.0.1'
    implementation 'com.google.firebase:firebase-messaging:17.3.3'
    implementation 'com.google.firebase:firebase-appindexing:16.0.2'
    implementation 'com.google.firebase:firebase-auth:16.0.5'
    implementation 'com.google.firebase:firebase-database:16.0.4'
    implementation 'com.google.firebase:firebase-config:16.0.1'
    implementation 'com.google.firebase:firebase-invites:16.0.4'
    implementation 'com.google.firebase:firebase-functions:16.1.1'
    implementation 'com.google.firebase:firebase-core:16.0.4'

Any idea what could be causing this.
