TypeError: obj.nodes is not iterable at convert

I got this error, and I think i'm submitting a request where this is a string and not JSON?

I'm working from code in publiclab/Leaflet.DistortableImage#485 and i realized, we are sending a string, not JSON -- because https://github.com/publiclab/mapknitter-exporter-sinatra#usage actually wants a string! Here, we want JSON, not stringified. So we're all good but perhaps in the future we may need to catch this and convert stringified JSON to JSON.
