How to use computed attributes to display driver data with driverUniqueId

hello,
I can't display driver data with computed attributes. Here is my configuration in computed attributes

Help me configure please

Your computed attribute doesn't make any sense to me. It doesn't look like you tried anything seriously.

hi, @Anton Tamanaev

as I don't know how to do computed attribute i added I added to traccar.xml

<entry key='processing.copyAttributes.enable'>true</entry>
<entry key='processing.copyAttributes'>driverUniqueId</entry>

and generated the report again but driverUniqueId not display. help me to display driverUniqueId

Can you explain why you're using attribute copying? How is it supposed to solve your problem?

I added because I did some research on the forum or elsewhere we managed to display with attribute. I just deleted and tried again computed attribute.
I tested it on the vehicle that has ibutton and it displays an error as illustrated in the screenshot

On another platform it works as illustrated in the screenshot

But on traccar server I can't get driverUniqueId to appear. My question is to know what computed attributes I must put to make the driver ID appear?

You haven't provided any information at about your device, protocol etc.

My device is Teltonika FMB130, protocole teltonika and pot 5027, all data is displayed except driver ID

And have you checked that the device is actually sending it? I mean validated the raw hex data from logs.
