when collection is converted to json, query property have weird schema

[mfaizan1]

I have tried 2 ways to do this both resulted in same

Directly manipulating url

    const request = new Request({
      header: requestHeader,
      url: `${apiEndpoint}?${new URLSearchParams(params).toString()}}`,
      method: 'GET',
      auth: null,
    });

using QueryParam

    Object.keys(params).forEach((key) => {
      const queryParams = new QueryParam({
        key,
        value: params[key],
      });
      request.addQueryParams(queryParams);
    });

both result into query property like this

"query": [
	{
		"key": "members",
		"value": {
			"prop1": {
				"key": "keyName",
				"value": "VALUE"
			},
			"prop2": {
				"key": "keyName2",
				"value": "VALUE2"
			},
		]
	},
	{
		"key": "reference",
		"value": {
			"prop1": {
				"key": "keyName",
				"value": "VALUE"
			},
			"prop2": {
				"key": "keyName2",
				"value": "VALUE2"
			},
		}
	},
	{
		"key": "Type",
		"value": {
			"_postman_propertyName": "QueryParam",
			"_postman_propertyIndexKey": "key",
			"_postman_propertyAllowsMultipleValues": true
		}
	},
	{
		"key": "_postman_listIndexKey",
		"value": "key"
	},
	{
		"key": "_postman_listAllowsMultipleValues",
		"value": true
	}
],

when this data is imported into postman it results in this url
{{url}}?members&reference&Type&_postman_listIndexKey=key&_postman_listAllowsMultipleValues

I cross checked by exporting postman collection and there query is array of objects

{
	"key": "KEY1",
	"value": "VALUE1"
},
{
	"key": "KEY2",
	"value": "VALUE2"
},

This happens when using collection.toJSON(), when request.toJSON() is used it in expected format.
