Unable to start receiver AlarmManagerSchedulerBroadcastReceiver: Attempt to invoke method 'android.net.Uri.getQueryParameter()' on a null object

I recently started getting this crash for my application in production.

Full StackTrace is as following :

Fatal Exception: java.lang.RuntimeException: Unable to start receiver com.google.android.datatransport.runtime.scheduling.jobscheduling.AlarmManagerSchedulerBroadcastReceiver: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.net.Uri.getQueryParameter(java.lang.String)' on a null object reference

I could reach to the code of AlarmManagerSchedulerBroadcastReceiver and it is as follows :

package com.google.android.datatransport.runtime.scheduling.jobscheduling;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Base64;
import com.google.android.datatransport.runtime.TransportContext;
import com.google.android.datatransport.runtime.TransportRuntime;
import com.google.android.datatransport.runtime.TransportContext.Builder;
import com.google.android.datatransport.runtime.util.PriorityMapping;

public class AlarmManagerSchedulerBroadcastReceiver extends BroadcastReceiver {
   public AlarmManagerSchedulerBroadcastReceiver() {
    }

public void onReceive(Context context, Intent intent) {
    String backendName = intent.getData().getQueryParameter("backendName");
    String extras = intent.getData().getQueryParameter("extras");
    int priority = Integer.valueOf(intent.getData().getQueryParameter("priority"));
    int attemptNumber = intent.getExtras().getInt("attemptNumber");
    TransportRuntime.initialize(context);
    Builder transportContext = TransportContext.builder().setBackendName(backendName).setPriority(PriorityMapping.valueOf(priority));
    if (extras != null) {
        transportContext.setExtras(Base64.decode(extras, 0));
    }

    TransportRuntime.getInstance().getUploader().upload(transportContext.build(), attemptNumber, AlarmManagerSchedulerBroadcastReceiver$$Lambda$1.lambdaFactory$());
}

}

I searched the entire codebase-scope and found that This BroadcastReceiver is being used from :

<?xml version="1.0" encoding="utf-8"?>

I could find that AlarmManagerScheduler is triggering this :

package com.google.android.datatransport.runtime.scheduling.jobscheduling;



public class AlarmManagerScheduler implements WorkScheduler {
private static final String LOG_TAG = "AlarmManagerScheduler";
static final String ATTEMPT_NUMBER = "attemptNumber";
static final String BACKEND_NAME = "backendName";
static final String EVENT_PRIORITY = "priority";
static final String EXTRAS = "extras";
private final Context context;
private final EventStore eventStore;
private AlarmManager alarmManager;
private final SchedulerConfig config;
private final Clock clock;

public AlarmManagerScheduler(Context applicationContext, EventStore eventStore, Clock clock, SchedulerConfig config) {
    this(applicationContext, eventStore, (AlarmManager)applicationContext.getSystemService("alarm"), clock, config);
}

@VisibleForTesting
AlarmManagerScheduler(Context applicationContext, EventStore eventStore, AlarmManager alarmManager, Clock clock, SchedulerConfig config) {
    this.context = applicationContext;
    this.eventStore = eventStore;
    this.alarmManager = alarmManager;
    this.clock = clock;
    this.config = config;
}

@VisibleForTesting
boolean isJobServiceOn(Intent intent) {
    return PendingIntent.getBroadcast(this.context, 0, intent, 536870912) != null;
}

public void schedule(TransportContext transportContext, int attemptNumber) {
    Builder intentDataBuilder = new Builder();
    intentDataBuilder.appendQueryParameter("backendName", transportContext.getBackendName());
    intentDataBuilder.appendQueryParameter("priority", String.valueOf(PriorityMapping.toInt(transportContext.getPriority())));
    if (transportContext.getExtras() != null) {
        intentDataBuilder.appendQueryParameter("extras", Base64.encodeToString(transportContext.getExtras(), 0));
    }

    Intent intent = new Intent(this.context, AlarmManagerSchedulerBroadcastReceiver.class);
    intent.setData(intentDataBuilder.build());
    intent.putExtra("attemptNumber", attemptNumber);
    if (this.isJobServiceOn(intent)) {
        Logging.d("AlarmManagerScheduler", "Upload for context %s is already scheduled. Returning...", transportContext);
    } else {
        long backendTime = this.eventStore.getNextCallTime(transportContext);
        long scheduleDelay = this.config.getScheduleDelay(transportContext.getPriority(), backendTime, attemptNumber);
        Logging.d("AlarmManagerScheduler", "Scheduling upload for context %s in %dms(Backend next call timestamp %d). Attempt %d", new Object[]{transportContext, scheduleDelay, backendTime, attemptNumber});
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this.context, 0, intent, 0);
        this.alarmManager.set(3, this.clock.getTime() + scheduleDelay, pendingIntent);
    }
}
}

I don't understand, why intent.getData() is getting null?

Can someone help me in resolving this crash?
