Research direction

Inspect src/main/java/com/google/firebase/messaging/FirebaseMessaging.java around line 226, starting with the validation applied by FirebaseMessaging.sendEach. Confirm whether the 500-message restriction still applies, then locate the relevant tests and update them so completion is demonstrated by handling a list larger than 500 without that validation error.

[REQUIRED] Step 2: Describe your environment
  • Operating System version: N/A
  • Firebase SDK version: 9.4.2
  • Library version: _____
  • Firebase Product: messaging (auth, database, storage, etc)
[REQUIRED] Step 3: Describe the problem

sendEach has a limit of 500 messages, this limit is probably a leftover from sendAll which no longer works. It's not really logical to have this limit anymore.

https://github.com/firebase/firebase-admin-java/blob/master/src/main/java/com/google/firebase/messaging/FirebaseMessaging.java#L226

Steps to reproduce:

Create a list with over 500 messages / push notifications. Call FirebaseMessaging.sendEach with the list. An error is thrown that there is over 500 messages in the array.
What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

Relevant Code:
    checkArgument(immutableMessages.size() <= 500,
        "messages list must not contain more than 500 elements");
