VError: apn write timeout

Recently I am getting this error after sending about 11k push messages of 22k. The app was restarted and the behavior is the same.

VError: apn write timeout

}

It seems the push messages are still processed by Apple.

Are you sending these pushes using Parse Server or node-apn directly?

[cbratschi]

They are sent through @parse/node-apn.

You can increase the timeout using the requestTimeout option in the config object and/or set your app to retry the message that has timed out.

I only see requestTimeout in the documentation but not in the source code. Is this value still being used and how can it be set?

[cbratschi]

Well, found it in the source code but somehow GitHub search did not list it. We have a lot of tokens and therefore it will take longer for later tokens. I will try it and update this ticket later.

[cbratschi]

Set the timeout to 30 s and now the requests work fine.

I had the same error message popup and in my case it was because I didn't define a topic for the notification. (I am upgrading from an old version of node-apn).
