'NoneType' object has no attribute 'get' #63 fixed with DDDOH answer

FYI: this PR did not fix the issue for me.
Some observations:

• the following similar line still contains old-style names. I faced error on here as well.
• Even after I fixed it, I see the following error

  ⠏ Querying projectTraceback (most recent call last):                                                                                                                                    [0/404]

UPD: adding json_content = json_content["projects"] to the top of filter_projects function seems to fix this. I can even download pdfs, but syncing still does not work due to a problem described in #62 (does not appear to be working).
UPD2: #66 did work
