A sample of the POST body request:

{
    "metadata": {
        "configurationVersions": [
            7
        ],
        "clusterVersion": "1.226.116.20211006-093312"
    },
    "id": "f0ec694c-c89e-4735-8821-5f082c522ecf",
    "name": "Host",
    "description": null,
    "rules": [
        {
            "type": "HOST",
            "enabled": true,
            "valueFormat": null,
            "propagationTypes": [],
            "conditions": [
                {
                    "key": {
                        "attribute": "HOST_OS_TYPE",
                        "type": "STATIC"
                    },
                    "comparisonInfo": {
                        "type": "OS_TYPE",
                        "operator": "EXISTS",
                        "value": null,
                        "negate": false
                    }
                }
            ]
        }
    ],
    "entitySelectorBasedRules": []

How can I parse the rules and avoid the null value?

What environment are you setting the variables from the GET response body? Or what would you see if you console logged rules on line 3 in the Pre-req script?

Additionally, it is not necessary to assign the rules or entity to the environment scope since the value is used within the run you could assign it to local scope using pm.variables.set(name, value)
