B4J Question PushServer Exception when sending push notifications

[Marco Iannaccone]

I've an iOS app currently sending the token for push notifications to the B4J PushServer app, that correctly stores it.

When trying to send a test notification from a web browser, anyway, using a string like this:
http://[HOST]:51044/send?password=[PWD]&text=Message
I don't receive any notification, and the PushServer generates this exception:

The web browser shows:
Message sent to 3 device(s).

 

[Erel]

The token is invalid.

Add Log("device: " & device) before the call to WriteItem in iOSPush and post its value.

Note that it is easier to use Firebase instead.

I investigated further and noticed there was one invalid (with shorter length) device token I had sumbitted manually with a test from the web browser. I removed it and everything's working, now.
Sorry for asking before checking all the submitted data.
