BLE DFU Mcu Mgr Error: NOT_SUPPORTED (8)

I am testing the DFU via BLE and get the message "NOT_SUPPORTED (8)"
Does anyone have an idea what is not supported?

Hi,

It looks like it doesn't support reading image state. Perhaps image manager is disbaled on the device? 

What example are you using on your device? And which SDK are you using?

You could also try using nRF Connect Device Manger app.
