[main.txt](https://github.com/audreyr/standardjson/files/3171036/main.txt)

dont know what to make of it

Start with the attached main.txt and the traceback at main.py line 10, where json.load receives the reported value. Determine whether the report identifies a reproducible problem in this repository or an issue in the user's script; a contribution would need a clearly scoped, reproducible failure and a corresponding test or documented resolution.
