[DeviantArt] Filter by Image Ratio

I'm trying to create a filter that applies a post-processor if the image is of a certain ratio - greater or less than 2:1 height:width. However, nothing I try is working, including the ["width >= 1200", "width/height > 1.2"] example given on the documentation page. It simply doesn't recognize "width" as a valid argument, despite the fact that it shows up when I run with the -K flag (content['width'] 1500 ).

Failed attempts (attempting a width-under-2k filter for simplicity):

          "filter": "{content[width]} < 2000",
          "filter": "{width} < 2000",
          "filter": "width < 2000",
          "filter": "(width < 2000)",
          "filter": "'width' < 2000", (this one it's understandably unhappy because I'm comparing a string and an int)
          "filter": ["width < 2000"], (this one just isn't recognized as a filter at all, despite matching the docs page best.)

Here's the error I get, in all cases except those last two:

C:\Users\USERNAME\gallery-dl\deviantart\sandara\Windsurfing-sandara-931293806.jpg[deviantart][error] An unexpected error occurred: NameError - name 'width' is not defined. Please run gallery-dl again with the --verbose flag, copy its output and report this issue on https://github.com/mikf/gallery-dl/issues .

And here's the output with the --verbose flag:

Here's the postprocessor with the filter that I was using in this particular case.

        {
          "name": "metadata",
          "filter": "width < 2000",
          "filename": "{title}-{author[username]}-{index}.html",
          "content-format": "\fT C:\\Users\\USERNAME\\gallery-dl\\templates\\da_template_lightbox.html"
        },
