As mentioned earlier that you need to check if any string literal is not closed properly. So please check your JSON data specially around 258 character to find the issue.
Unterminatedstring at 258
Looks like the problem is somewhere neat string "lidedonde usci la farafalla ...." string which seems to be abruptly coming in your JSON file. I guess the bad characters are causing newline characters here somwhere near "riconobbe" and after "Dostoevskij" words.
"msg":"Una crisalidedonde usc?? la farfalla dellarteOgni scrittore russo vi si riconobbe Dostoevskij raccontiGogol https//tco/ygU33PW3uB"}
I guess if you open it in some good editor then you should be able to find those bad characters)
