TableView text color change work but with an error message, why?

[filipdns]

Hello, I'm using code below in QML to change the text color if condition:

itemDelegate: Text {
                  anchors.verticalCenter: parent.verticalCenter
                     color: listModel.get(styleData.row).activecheck === "inactive" ? "lightgrey": "black"
                     text: styleData.value
                }

it's working but I receive the error message :

TypeError: Cannot read property 'activecheck' of undefined

Do you know how can I solve that?

Thank you very much
