I ran into this error after upgrading/building traccar from source. After some searching, seemed like I should have used more official channels to upgrade. However, I had a tweak to the GT06 decoder that I needed to integrate. Anyway, for future reference for anyone running into this same error, I simply copied the schema files to the /opt/traccar/schema folder and it all works again. (I was upgrading from 6.10.0 to 6.14.4)
