Cognite functions

Are you referring to the output from the handle function in a Cognite Function? If so, this is more for status purposes. E.g., if your handle/function was successful you might have a dictionary returned as follows:

return {“status”: “success”, “message”: f“processed {len(total_data)} datapoints”}

This dictionary would then be viewable as a JSON from the Functions webpage in Fusion. Maybe if you were handling a failure you might also write something like:

return {“status”: “failure”, “message”: “no timeseries found”}

The functions referred to by @roman.chesnokov do not return any JSON values though (they actually return None). Does that make sense? If you don’t want to return anything in the handle function, then you could return an empty dictionary, but good practice would be to do something like above.
