When using --uncssrc it always fails

[pamtbaau]

When I use npx uncss -u uncss.json http://base-dev > ../css/style-uncssed.css, no matter the content of uncss.json a whole bunch of data is dumped and ../css/style-uncssed.css remains empty.

This is the tail of the dump:

          '@media (min-width: 576px) {\n' +
          '  .container-sm, .container {\n' +
          '    max-width: 540px;\n' +
          '  }\n' +
          '}\n' +
          '@media (min-width: 768px) {\n' +
          '  .co'... 197814 more characters,
        hasBOM: false,
        id: '<input css 1>'
      },
      end: { line: 64, column: 1 }
    },
    selector: ':root',
    lastEach: 1,
    indexes: {}
  }
}

Node.js v17.1.0

I've tried the following contents in uncss.json

{}

or

{
   "media": [
        "(max-width: 480px) and (orientation: landscape)"
    ]
}

or

{
    "media": [
        "(max-width: 480px)"
    ]
}

Whenever I run npx uncss -m "(max-width: 480px) and (orientation: landscape)" http://base-dev > ../css/style-uncssed.css, all goes well.

What am I missing?
