This happens because you have a recipe with a "/" in the name, that has an attached image. Fix for export without changing any code is to remove the "/" from any recipe name. E.g. change "w/" to "with"

Proper fix is to sanitise the generated image name to remove the "/"

Thanks for the report. I am open to merging a PR which fixes this accordingly.
