Getting Error While Testing PushNotification

When i try to test the Push Notification as per the ionic doc.

curl -k MyPrivateKEy: -H “Content-Type: application/json” -H “X-Ionic-Application-Id: MyAppID” -d ‘{“tokens”:[“MyDeviceToken”],“notification”:{“alert”:“I come from planet Ion.”}}’

After run the above code in command prompt i get error message as

Error: invalid json

Please help me to fix this issue. :frowning:

Why are you running this in node. This is supposed to be in front end not your backend.
