   • or
   • https://api.line.me/v2/bot/message/push, ContentType: application/json
4. If https://api.line.me is correct, enable 1 alert action. Simulate the alert action or wait for a new alert to be trigger
   • does it work now?
5. If yes, slowly enable all alerts for https://api.line.me/v2/bot/message/push
