How had you created your theme?

@hari007 An easy fix is to just hit the new theme button while the theme you want to export is active to duplicate the theme. Then you can export that.

Otherwise, go into the ZIP file and finding the id key in settings.json and set it to "", as the error message suggests, might work. Didn't try that when I encountered the same error.
