There was at somepoint an issue with MID when Ulrike was trying to update (create as it was first time) the config file (https://git.xfel.eu/gitlab/detectors/calibration_configurations/blob/master/202022/002693.yaml) using update_config script.
It generated erroneous yaml file where data-mapping section also has MID as a key however it should be karabo_id instead of MID. This issue will occur if the yaml file is generated first time from default.
