import recipe from json not working

[jjauzion]

I'm trying to import recipe from a json file and it doesn't work.

I tried to export an existing recipe so I get a the valid json format Tandoor is using, then I copy paste the json into the import field in Tandoor (Import Recipe > Source) but it doesn't work neither.

Here is an example of a json file I exported (so good json format) and I can't import it into Tandoor.
I have this error in the logs:

Jan 06 15:13:37Traceback (most recent call last):

Jan 06 15:13:37for key, val in nutrients.copy().items():
Jan 06 15:13:37AttributeError: 'NoneType' object has no attribute 'copy'

Any idea ? Is there something I'm doing wrong ?
