KeyError: 'dehydrated state'

Has anyone come across this before?

weight_data = client.get_measurements('Weight', single_date, single_date)
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

KeyError: 'dehydratedState'

Seems like an issue with client.py, any way to debug or fix this?

[hannahburkhardt]

I can't reproduce the issue. Can you provide a more detailed example? What are the weights that you are expecting to be returned?

This is the script I'm using, I'm essentially trying to get the date, weight, fat, carbs, protein, and calories for the past seven days off of MFP. I'm not sure what the "dehydrated state" issue even is. If I get rid of the try except block I get this error:

Seems like there's something in the client.py around "dehydratedState"? No idea what that means or how to fix that.

I second that. it only happened from yesterday onwards - it relates to getting a weight measurement.
