Hi Team,  
I’m using the below API

```auto
/inventory/managedObjects/${device_id}?withLatestValues=true

```

to get the latest measurement value in managedObject, but some time get the `500 Server error` whenever measurement missing in `c8y_LatestMeasurements object`

```auto
"c8y_LatestMeasurements": {
        "sol_TankMeasurement": {
            "DaysUntilDelivery(Total Flow Rate)": {

    }

```

Any suggestion, How we can fix it ?.

Hi,

I cannot follow exactly when you get the “500” error. Is it when the last measurement you received does not have a value for a specific series?

Anyway, to me this looks like an issue for which you should create a ticket with Cumulocity support:
