Parse-Server Crash on APNs Timeout

[doodyparizada]

Transferred from parse-community/parse-server#3637

Issue Description

Using the REST endpoint for sending APNS push, sometimes the service times out and causes parse-server to crash...

Steps to reproduce

Just running this following curl a few times until the app crashes:

curl -H 'X-Parse-Application-Id: XXX' \
     -H 'X-Parse-Master-Key: XXX' \
     -d '{"where": {"user": {"$inQuery": {"className": "_User", "where": {"objectId": {"$in": ["UID1", "UID2"]}}}}}, "data": {"title": "my title", "alert": "mi alert"}}' \
     'http://localhost:1337/parse/push'

Expected Results

parse-server should catch the exception and either retry or fail with an error message (not crash the whole process).

Actual Outcome

parse-server is crashing on:

/parse/node_modules/parse-server/lib/ParseServer.js:401
            throw err;
            ^

Error: Connect timed out
    at Connection.<anonymous> (/parse/node_modules/apn/lib/connection.js:226:36)
    at tryOnTimeout (timers.js:224:11)
    at Timer.listOnTimeout (timers.js:198:5)

Logs/Trace

I caught two types of crashes:

ERR! parse-server-push-adapter APNS cannot find vaild connection for b73bd323f4e1a5427a82e2463c79e0b9cb34f95e8154e78ce7a2511021282ec5
/parse/node_modules/parse-server/lib/ParseServer.js:401
            throw err;
            ^

    at _combinedTickCallback (internal/process/next_tick.js:67:7)
    at process._tickDomainCallback (internal/process/next_tick.js:122:9)

But my certificate is not expired - retrying works.

and:

/parse/node_modules/parse-server/lib/ParseServer.js:401
            throw err;
            ^

Error: Connect timed out
    at Connection.<anonymous> (/parse/node_modules/apn/lib/connection.js:226:36)
    at tryOnTimeout (timers.js:224:11)
    at Timer.listOnTimeout (timers.js:198:5)

just timing out on the connection.

I see the same behavior. It would be far nicer to properly catch the error and not blow up.

[woodardj]

Same. We just had a cert expire and it crashes the whole app. Pretty bad failure mode.

And as mentioned many times, we won’t fix this one. This is inside the node APN module, feel free to open an issue there.
