add manually listObject in custom action for testing

Hi all, 

Did someone ever hardcoded a listObject in custom action? my object is defined and working when using the aep data field directly but I’m doing some troubleshooting as I’m suspecting my custom action is failing when a field has special charater.
[
        {
            "parent_SKU": "",
            "child_SKU": "",
            "pdpURL": "",
            "largeImage": "",
            "title": ""
        }
    ]

Thanks,
