2) Comment these two lines in notification object

  **// category: null, // (optional) default: null
  // userInfo: null, // (optional) default: null (object containing additional notification data)**
  **number: 10, // (optional) Valid 32 bit integer specified as string. default: none (Cannot be zero)**
