[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

We are sending about 30k pushes to devices, 50% of this messages (iOS and Android) receives this error as response. We've already tried:

• Generating new tokens for devices we own.
• Change to debug/release projects.

Error: Requested entity was not found.

Relevant Code:

let unifiedFirebase: app.App;

const initializeFirebases = async () => {
  const { iosParameters, unifiedFirebaseParameters } = await initializeParameters();
  await elk.info('Intializing firebase');
  if (!iosFirebase) {
    iosFirebase = await initializeGoogleServices(iosParameters,
                                                 'project_name_removed');
  }
  if (!unifiedFirebase) {
    unifiedFirebase = await initializeGoogleServices(unifiedFirebaseParameters,
                                                     'project_name_removed');
  }
  await elk.info('Intialized firebase');
};


const sendAndroidPush = async (androidToken: any, pushData: pushData, payload: any) => {
  const { title, body } = pushData;
  try {
    await sendPushMessage(title, body, androidToken, payload, unifiedFirebase, false);
    return true;
  } catch (e) {
    const errorDetails: any = Object.assign(pushData, {});
    errorDetails.stackTrace = e.stack || null;
    await elk.error('error_android_send_push', errorDetails);
    return false;
  }
};

const sendPushMessage = async (title:string, body:string, token:string, data: any,
                               firebaseApp: app.App, isTest:boolean) => {

  const message: FirebaseMessage = {
    token,
    notification : {
      title,
      body,
    },
  };

  if (data && Object.keys(data).length > 0) message.data = data;

  return firebaseApp.messaging().send(message, isTest);
};

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
