KeyError: 'The data column ceiHei from file /usr/local/testing/testcase2/models/Resources/weather.csv does not match any of the allowed column keys and therefore it cannot be saved within the compiled fmu. Test case data variables are used for forecasting and KPI calculation. If you want this variable to be part of the test case data make sure that the column has a key with any of the specified formats in categories.json and that, if it is a zone related key, it is in the format: variable[zone_identifier] '

In particular, the weather bus output celHei was changed to ceiHei, requiring the same change to data/categories.json.
