No JSON object could be decode

[aminehmida]

I got this exception when trying to list my files. I think it has something to do with shared folders but I'm not sure.
IPYTHON trace :

Ive also ran into this issue while trying to download from a url, however only sometimes I believe it may be the request taking too long to respond.
