Instapy: Running error suddenly occurring, no previous issue with script

[Dankartpage]

Script has been working perfectly fine for weeks until now, here's the traceback.

$ python quickstart.py

(edit: tried to update the files by doing git pull before posting this issue)

Found solution:

"It possibly happened after you've forcibly ended some session where it corruptly dumped data to JSON file,
for solution, either find that corrupt element in followRestriction.json file and fix it or just reset that file (keep only this in there: {})

note that followRestriction.json file keeps records to be used with follow_times parameter"

Solved by deleting followrestiction.json file (attempting to git pull to replace it, but don't think this made any difference) and starting up the script again, works fine now. thanks alot to @uluQulu
