My $.02 is that this is pretty good behavior. The error message is very clear.

An improvement would be to fail fast. I.e. we could validate the apns cert at startup if configured and fail with the above error right away rather than waiting for a push?

What did you have in mind? I don't really like the idea of logging a warning and carrying on. Again, my $.02 and I'm interested in what others think....

[gateway]

Well it crashes the server for me which I wasn't expecting. Also if your haven't restarted the server in a while you will never potentially see its expired , or will it spit something out when a push tries to go out?

Its the first time I saw this and its not a huge deal since its our staging server but thought I would bring it up for a conversation.

[funkenstrahlen]

Maybe this should better be discussed in the parse-server-push-adapter repository?

[bnol]

+1

[funkenstrahlen]

I also think this should just throw an error but not crash the server. It is a problem if push notifications do not get send out but it should not crash all other server functionality.

[bnol]

Any plan working on this issue yet? =/

[bnol]

@funkenstrahlen you're a contributor of parse-server-push-adapter, aren't you? This error happens in parse-server-push-adapter which is using a very old release of node-apn (1.2.0, 2.1.3 is the current release). Any plan for updating it? :)

UPDATE: I also opened an issue on parse-server-push-adapter project :)

[funkenstrahlen]

@bnol There is already a PR for updating the node-apn: parse-community/parse-server-push-adapter#52

[flovilmart]

@bnol, apn 1.2 is not old and is correctly working. I believe the package throws and for a good reason. You should probably open an issue on the apn package repository if you believe this is an issue.

[bnol]

@flovilmart the problem is we have no better way to handle that error for now (to avoid the server to be crashed). Or is there any way to work around with it?

[flovilmart]

Have a valid certificate?

[bnol]

@flovilmart we sure will update the cert. But in this case, crashing the whole process should never be an expected behaviour. I think we could make it better. :)

[flovilmart]

Not sure that's our responsibility in this module, probably in APNs node-apn/node-apn#541
