Results must be an array, got: object in Zapier?

I am using search in Zapier. I have my own API which sends a single object when I search item by its item Id.

Below is response from API

{
    "exists": true,
    "data": {
        "creationDate": "2019-05-23T10:11:18.514Z",
        "Type": "Test",
        "status": 1,
        "Id": "456gf934a8aefdcab2eadfd22861",
        "value": "Test"
    }
}

when i search this by zap

Results must be an array, got: object, ({"exists":true,"data":{"creationDate":"2019-05-23T10:11:18.514Z)

Below is the code

module.exports = {
    key: 'item',
    noun: 'itemexists',
    display: {
        label: 'Find an item',
        description: 'check if item exist'
    },

    operation: {.
        inputFields: [
            {
                key: 'itemid',
                type: 'string',
                label: 'itemid',
                helpText: 'Eg. e3f1a92f72c901ffc942'
            }
        ],

        perform: (z, bundle) => {
            const url = 'http://IP:8081/v1/itemexists/';
            const options = {
                params: {
                    itemId: bundle.inputData.itemid
                }
            };


            return z.request(url, options)
                .then(response => JSON.parse(response.content));
        },
        sample: {
            "exists": true,
            "data": {
                "creationDate": "2019-05-23T10:11:18.514Z",
                "Type": "Test",
                "status": 1,
                "Id": "456gf934a8aefdcab2eadfd22861",
                "value": "Test"
    }
},
    }
};

The data you return from your perform must be of type "Array" (which starts with [. You returned an object (a structure starting with {).

The fix is simple enough - wrap your returned data in square brackets.

.then(response => [JSON.parse(response.content)]); // note the added `[]`

// or, if you don't care about the `exisits` key
.then(response => {
  const data = JSON.parse(response.content)
  return [data.data]
});
