[READ] Step 1: Are you in the right place?
  • For issues related to the code in this repository file a Github issue.
  • If the issue pertains to Cloud Firestore, read the instructions in the "Firestore issue"
    template.
  • For general technical questions, post a question on StackOverflow
    with the firebase tag.
  • For general Firebase discussion, use the firebase-talk
    google group.
  • For help troubleshooting your application that does not fall under one
    of the above categories, reach out to the personalized
    Firebase support channel.
[REQUIRED] Step 2: Describe your environment
  • Operating System version: Docker version 28.0.1, build 068a01e (image is: oven/bun:1.2.12-alpine)
  • Firebase SDK version: 13.4.0
  • Firebase Product: messaging
  • Node.js version: v20.18.0
  • NPM version: 10.8.2
[REQUIRED] Step 3: Describe the problem
Steps to reproduce:

When using Http/2 with sendEachForMulticast will throw an error (Error while making requests: GOAWAY - exceeded_max_concurrent_streams, Error code: 1) when sending with a lot fcm tokens (lowest that i have tested that got rejected is 214)

if legacy http transport is enabled, this issue does not occur.

best guess why this happens is the fact that it sends a request for every token, therefore sending up to 500 requests at once which is too many for the http/2 implemenation of it.

Relevant Code:
const app = admin.initializeApp();
const messaging = app.messaging();

const tokens = []; // List of a lot of FCM tokens

try {
    const result = await messaging.sendEachForMulticast({ tokens });
} catch (err) {
    console.error(err);
}
