Why Is Push Notification Failing With the "Requestedentitywasnotfound" Error?

Problem

Push notifications are failing due to the "Requestedentitywasnotfound" error.

Explanation

This error occurs when the FCM token you are trying to use to send a push is no longer registered. It is treated the same as a "NotRegistered" error, meaning the app may have been uninstalled.

Solution

Perform the following steps:

  1. Reconnect to the database.
  2. Ensure all tokens are active and in use.
  3. Delete or update any unused tokens.
