The plugin runs EPUBCheck in JSON mode. If you got this message, either no JSON file was generated at all or the JSON file was invalid, which is relatively rare. You also might want to use the Python
3 interpreter that comes with Sigil.
(I only mentioned Python
2, because some Sigil users are still using very old Sigil versions.)

That is a
macOS error message. It looks like you'll have to install a JDK.
