Suddenly getting "Request contains an invalid argument" for sending notifications, it was working before

[REQUIRED] Step 2: Describe your environment

• Operating System version: Google App Engine (F4_1G)
• Firebase SDK version: 10.0.2
• Firebase Product: firebase-admin/messaging
• Node.js version: 14
• NPM version: v6.14.17

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

I’m sending push notifications to both iOS/android devices, looking at my analytics it seems that the iOS notifications are not arriving anymore. I’m getting messaging/invalid-argument, with errorMessage: Request contains an invalid argument. The notifications I’m sending look like this:



{
              notification: { 
                title: 'alarmName', 
                body: 'pushMessage',
              },
              data: {
                uid: 'user_id'
              },
              apns: {
                payload: {
                  aps: {
                    badge: 2,
                  },
                },
              },
              android: {
                priority: 'high',
                notification: {
                    sound: 'default',
                    notification_priority: 'PRIORITY_HIGH',
                    visibility: 'public'
                }
              },
              token: 'fcm_token',
}

There is an array of messages like this, I’m sending with messaging.sendAll(). I’m sending these messages on a daily basis, the issue started on the 9th of May. Anything changed in the firebase sdk, or perhaps apple side?

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hello @PaulvanMotman I would suggest contact Firebase support https://support.google.com/firebase/?hl=en where you can share your details including Firebase project number and the support team will help the debugging. Thanks!

@chong-shao You linked to a FAQ, there is no form to file a bug report?

I also face with this while sending to iOS devices with following apns config:

{
  payload: {
    aps: {
      contentAvailable: true,
    },
  },
  headers: {
    "apns-priority": "10",
    "apns-push-type": "background",
  },
}

it works for android targets.
