How to specify sound and click_action in firebase cloud function

问题

I tried with the following function (node.js v8):

exports.sendComNotification = functions.firestore
  .document('Comunicados/{comID}')
  .onUpdate((snap, context) => {
    console.log('Com triggered');
    const newValue = snap.after.data();
    const msg = newValue.title;
    var message = {
      notification: {
        title: 'Comunicado da Diretoria!',
        body: msg,
        badge: '1',
        sound: 'default',
        click_action: 'FLUTTER_NOTIFICATION_CLICK',
      },
      topic: "Comunicados"
    };
    return admin.messaging().send(message)
      .then((response) => {
        console.log('Successfully sent message:', response);
        return
      })
      .catch((error) => {
        console.log('Error sending message:', error);
        return
      });

  });

But that gives the following error in the fucntions log:

Error sending message: {
    Error: Invalid JSON payload received.Unknown name "badge"
    at 'message.notification': Cannot find field.
    Invalid JSON payload received.Unknown name "sound"
    at 'message.notification': Cannot find field.
    Invalid JSON payload received.Unknown name "click_action"
    at 'message.notification': Cannot find field.
    at FirebaseMessagingError.FirebaseError[as constructor](/srv/node_modules / firebase - admin / lib / utils / error.js: 42: 28)

If I take out "badge", "sound" and "click_action", it works, but then there's no sound upon receival and the actions defined in onResume (flutter app) don't fire either, of course. What would be the correct way of setting the sound and click_action props? Thanks in advance.

Ok, I finally managed to gather bits and pieces here and there to make it work. Don't understand why the docs do not have a clear and direct path to such a common requirement.

exports.sendComNotification = functions.firestore
  .document('Comunicados/{comID}')
  .onCreate((snap, context) => {
    const doc = snap.data();
    const msg = doc.title;
    var message = {
      notification: {
        title: 'Comunicado da Diretoria!',
        body: msg
      },
      data: {
        title: 'Comunicado',
        body: msg
      },
      android: {
        notification: {
          sound: 'default',
          click_action: 'FLUTTER_NOTIFICATION_CLICK',
        },
      },
      apns: {
        payload: {
          aps: {
            badge: 1,
            sound: 'default'
          },
        },
      },
      topic: "Comunicados"
    };


    return admin.messaging().send(message)
      .then((response) => {

        console.log('Successfully sent message:', response);
        return
      })
      .catch((error) => {
        console.log('Error sending message:', error);
        return
      });

  });
