Incorrect UI code validation for colon in parameters of method

[OKhalkov]

Payload:

{
    "temperatureUploadFrequency": 60,
    "humidityUploadFrequency": 30
}

Code:

var key = [];
foreach(element: msg.entrySet()){
    key.add(element.key);
}

var result = {
    contentType: "JSON",
    data: key,
    metadata: {
        deviceId: "deviceIdTuya"
    }
};

return result;

But the code performs correctly
