sort_by throws in json_printer when the path is not specified on a check.

[FiliSantillan]

Setting Theme-Check, I realized that whenever I add the token. It throws me an error: Error: Unexpected end of JSON input..

If I remove the "token" option, everything works perfectly.

This is my theme-check.yml file:

name: Theme Check

on:
    pull_request:
        branches: live

jobs:
    theme-check:
        name: Theme Check
        runs-on: ubuntu-latest
        steps:
            - uses: actions/checkout@v2
            - name: Theme Check
              uses: shopify/theme-check-action@v1
              with:
                  theme_root: "."
                  token: ${{ github.token }}

This is what the action returns:

Run shopify/theme-check-action@v1
  with:
    theme_root: .
    token: ***

Oh darn. That's a theme-check bug with the json printer. I'll get that fixed ASAP. Thanks for the report!

[charlespwd]

Should be fixed now :)
