Unable to retrieve the asset entitlements

Hi, 

I'm using the asset-entitlements API and I'm unable to retrieve the information for the asset SNJ2YMKG3. The API is working for other assets.

Here's a sample of the response:

https://apigtwb2c.us.dell.com/PROD/sbil/eapi/v5/asset-entitlements?servicetags=SNJ2YMKG3

[
    {
        "id": null,
        "serviceTag": "SNJ2YMKG3",
        "orderBuid": null,
        "shipDate": null,
        "productCode": null,
        "localChannel": null,
        "productId": null,
        "productLineDescription": null,
        "productFamily": null,
        "systemDescription": null,
        "productLobDescription": null,
        "countryCode": null,
        "duplicated": false,
        "invalid": true,
        "entitlements": []
    }
]

Am I doing something wrong ?

Thank you,
