I am trying to send the following json push based on onesignal documentation

{ "alert": "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque pellentesque bibendum tellus id.", "large_icon": "http://www.nairobi.go.ke/themes/fitimage/images/ncclogo.png", "big_picture": "https://investinkenya.co.ke/components/uploads/a463f6df96138fb39a0ac1ca89db9965.jpg", "title": "Welcome to NCP" }
