JSONDecodeError: Expecting value

[Zanonia]

Hello

I have this error since today, whereas the script had been running without problems for months and nothing has changed on my system :

Traceback (most recent call last):

Edit :
Apparently, the problem was due to poor data formatting in db.json.
I don't understand how this happened.
I solved the problem by rewriting a new db.json manually.

Hello,

That's weird, have you edited db.json by hand? I can't see any other situation where that could happen (or that would be a serious bug in the json python stl which I can't expect to happen for those kind of simple situations)

I didn't touch the db.json until t2m crashed.
I kept a copy of the original, I think the problem is the comma on line 259:

            865582743744385024,

Can a large number of tweets to be transferred and a too frequent call of the script (the cron was on a 2min interval at this time) cause this kind of problems?

I also noticed in Nginx's error log that when the media attached to a tweet exceeded the size limit of the instance (1MB on mine), an upload was attempted every time you use t2m and this for several days.
I don't know if that deserves to open a new issue.
