@TahaTesser Thanks for getting back to me and sorry for taking so long to reply. I wanted to dedicate some proper time to this to properly replicate your example. I've now managed and my problem remains - your example doesn't work for me. I do observe the same I did before: the message enters the device, I get some odd message, but it doesn't reach the message handler. The message I get is the following. I copied your example ad verbatim. I sent messages using the following curl command which was confirmed to work with display messages but not data messages. curl -X POST -H "Authorization:Bearer <access_token>" -H "Content-Type: application/json" -d '{
"message":{
"token":"<token I grabbed from the device's logs>",
"data":{
"id":"3",
"status":"This be a test"
}
}
}' https://fcm.googleapis.com/v1/projects/<firebase-project>/messages:sendMy worry is that I set up something else incorrectly but I can't for the life of me think of what else has changed because this definitely used to work. Something I feel insecure about for example is |

@TahaTesser That is a display message because it has a notification property and as I said those work fine. This problem is about data messages. Please look at the error message I reported above (I'll replicate it here) |

I'm sure the warning message contains some useful indication but I'm not experienced enough with iOS to interpret it. |

I now understand this appears to be a duplicate of #3395 which is still open. |

Bug report
Describe the bug
The
onMessagehandler is no longer called for data messages on iOS in the foreground. It is called for data messages on Android in the foreground, and it is called for display messages on iOS in the foreground.Steps to reproduce
Steps to reproduce the behavior:
onMessagehandler in the appExpected behavior
I would expect the
onMessagehandler to be called for data messages in the foreground. This is supposed to be the simple scenario. This used to work.Additional context
I have tried different data messages to see if my format is the culprit, to see if something's changed. To no avail (and note that they still work fine for Android).
Here is what I would normally send (no longer works - just iOS in foreground though):
{ "data": { "type": "friend-request:cancelled", "action": "deleted", "collection": "incoming-friend-requests", "userId": "tr5EajFZpubvNypZxAGc3SnykWc2" }, "android": { "priority": "normal" } }(EDIT) I just saw this pop up in XCode whenever I would send a data message and I could not figure out how it's related but I suppose it must be.
I figured this was related to these lines in
AppDelegate.swift.Yet when I removed these, I no longer received display messages (notifications) in the foreground either. So those lines are working.. but only for display messages. Something is holding back my data messages.
I have also tried to add
content_availabletoapsbut no luck.The fact that it's worked before and I do still get display messages (notifications) in the
onMessagehandler with the app open in the foreground makes me think it can't be a configuration issue on my part.Flutter doctor
