That error is pretty vague sadly so I can’t tell what’s wrong. I’ll put up an issue on GitHub
Look's is looking only at the rune in position 0 in the JSON. There's maybe a way to define the rune position in the form? Or maybe having the script to look at all runes in the file for a match? Just ideas...

This isn’t about the rune. We reach your node but it’s not returning json.
