Bug description
I'm not entirely certain because I was not able to test it, but I believe the Data type microservice is missing some error handling in data_type_handler.py
For example, if one tries to cast "Hello world" into a float Python will return an error, but there's nothing to catch that error.
Expected result
Either replace the un-castable values by None, or abort the Data type command?
Actual result
Crash?
