so as you guess im learning json, and dont understand what this errors mean!, so thanks in advance!

Solution

  • It's clear that the JSON string you are feeding into the parser is garbage. Looking at the error messages, I would say it is probably caused by using an incorrect string encoding. You are probably expecting it to be UTF-8 and getting something else (or vice versa).
