Do not understand this error message: property schema:thumbnailURL: No property definition found

For example: "@type": "CreativeWorkSeries", "name": "Syllabus", "thumbnailURL": "https://profalbrecht.files.wordpress.com/2012/07/easycapture3.jpg", ...

It is a property; why does it need a property definition?

It is a JSON property, but not one defined in schedule,a.org. I suspect you want schematic:thumbnailUrl (note capitalization). The linter is complaining that your using an property (predicate) not defined in a vocabulary.
