myfitnesspal.Client('my_username') returns JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[jojo9289]

Hi,

first , my environment : Win10 Pro /anaconda 1.8.5 / python 3.6.4

After having stored my password with $myfitnesspal store-password my_username

the client connection with $client = myfitnesspal.Client('my_username') is returning below error and I cannot figure out what is wrong . Did you already experiment such error ?

thx in advance

I haven't seen such an error before, but it does look like the problem is probably rooted somewhere in authentication. Things I'd check are probably:

1. Are you sure you used the right username and password?
2. Are you sure the script was sending the right username and password? You could investigate that by strategically inspecting things using pdb around here: ~\Anaconda3\lib\site-packages\myfitnesspal\client.py in _login
3. Maybe the response isn't quite what we're expecting; you might want to look at what result.content is here: ~\Anaconda3\lib\site-packages\myfitnesspal\client.py in _get_auth_data

Good luck, and let me know if you need any other debugging tips; feel free to ask me questions on the gitter channel, too.

Solved ! It was due to a change of Privacy/ T&Cs in MFP which was pop up only in the web version . Once I hit the « consent » button, the API was back , behaving normally. Thx .

Awesome; I'm glad you figured it out!
