• For issues or feature requests related to the code in this repository
  file a Github issue.
• For general technical questions, post a question on StackOverflow
  with the firebase tag.
• For general Firebase discussion, use the firebase-talk
  google group.
• For help troubleshooting your application that does not fall under one
  of the above categories, reach out to the personalized
  Firebase support channel.

[REQUIRED] Step 2: Describe your environment

• Operating System version: iOS
• Firebase SDK version: 11.11.0
• Firebase Product: Messaging
• Node.js version: 16.13.1
• NPM version: 8.10.1

[REQUIRED] Step 3: Describe the problem

I'm attempting to set more particular fields into the messaging send() function, however I continue to get failures as messaging().send() validates the JSON.

Steps to reproduce:

What happened? How can we make the problem occur?
Any time I add apns-push-type I seem to get these failures

This will print Firestore logs to the console.

Relevant Code:

function sendOrderReady(token) {
  const date = new Date();
  return admin.messaging().send({
    token,
    apns: {
      headers: {
        'apns-push-type': 'liveactivity',
        'apns-priority': '10'
      },
      payload: {
        aps: {
          timestamp: date.getTime(),
          event: 'update',
          'content-state': {
            orderCompleteDate: date.toISOString(),
            orderReady: true
          }

        }
      }
    }
  })
