   @suresh-webonise can you clarify the structure of the facts? Specifically the role, name, and sport.
   If role is an array containing multiple roles you can do a contains check. If it's a single role you can use an equality check.

   For example:

   const facts = {
     id:1,
     username:'sureshk',
     student: {name:'zbc',percentage:100},
     role: 'coach',
     sport:'hockey'
   }
   
   const rule = {
      condition: {
         all: [
           {
              fact: 'id',
              operator: 'equal'
              value: 1
           },
          {
             fact: 'username',
             operator: 'equal',
             value: 'sureshk'
           },
           {
              fact: 'student',
              path: '$.name',
              operator: 'equal'
              value: 'zbc'
           },
           ...
         ]
       }
   }

   const fact={
     id:1,
     username:'sureshk',
     student:[{name:'zbc',percentage:100},{name:'zb',percentage:10}],
     role:['coach','mentor'],
     sport:['hockey','base']
   }
   
   const rule = {
   	event: {
   		type: "",
   		params: {}
   	},
   	conditions: {
   		all: [
                           {
   				fact: "student",
   				operator: "customContains",
   				value: [ 
                                    {
                                      "field": "name",
                                      "value": "zbc",
                                      "operator": "="
                                    },
                                    {
                                      "field": "percentage",
                                      "value": 100,
                                      "operator": "="
                                    }
                                   ]
   			},
   			{
   				fact: "id",
   				operator: "equal",
   				value: 1
   			},
   			{
   				fact: "username",
   				operator: "equal",
   				value: "sureshk"
   			},
   			{
   				fact: "role",
   				operator: "contains",
   				value: "coach"
   			},
   			{
   				fact: "sport",
   				operator: "contains",
   				value: "hockey"
   			}
   		]
   	}
   }

   I hadn't realized that students was an array of objects. In this case, I created a custom operator that searches for an object within an array.
