When selecting certain Bundesländer for the barplot a key-error occurs. Apparently a key named "startdate_action" is not found. This occurs for "Niedersachen" for instance.
This key is part of the actions-table and denoted when a certain action came into effect. I currently have no clue why this key apparently lands somewhere where it does not belong. What complicates the matter is that in the reported stacktrace there is not a single line which occurs within our code.
Also the error never reaches the top-level, i.e. Pycharm never sees this error. It just occurs in the web-fontend. It must be caught somewhere. So, it has to happen in some callback I suppose...
