New Issue Checklist

• [x] I can reproduce the issue with the latest versions of Parse Server and the Parse Server Push Adapter.

Issue Description

The http/2 implementation in firebase-admin throws on network errors instead of handling them, which lets them propagate to the node process, which eventually crashes the process.

• For GOAWAY errors a fix has been implemented with https://github.com/parse-community/parse-server-push-adapter/issues/340.
• For other network errors such as ECONNRESET there is no easy remediation.

The proper solution for any network error is to fix https://github.com/firebase/firebase-admin-node/issues/2789, for example via an event listener.

Steps to reproduce

This issue occurs on network error events, such as ECONNRESET.

Actual Outcome

Unhandled error crashes app.

Expected Outcome

Error should be handled by the firebase-admin.

Workaround

• Use the older version HTTP/1.1 by setting fcmEnableLegacyHttpTransport: true in your push options.
• Catch the error in a global Node process error handler.

Environment

Client

• Parse Server Push Adapter version: 6.8.0

Server

• Parse Server version: 7.3.0
