Give back error messages when something with a dataset upload went wrong

sebffischer opened this issue · 1 comments

Sometimes when uploading datasets there can be problems during the calculation of the qualities and the dataset stays "in_preparation" forever. It would be helpful if one could access what exactly went wrong e.g. with the evaluation engine.

Specifically it would be nice to warn that if the default target column contains NAs that this leads to issues with the calculation of qualities.
