Using Paper 1.16.4

[Nogapra]

I have the same issue with PaperMC 282 (MC 1.16.4)

I specify that my MAP files are stored in SQL and that I did not test with a brand new version, my card was generated with a 1.16.3 version of paper

@Baktus79 @Nogapra You both seem to be encountering a different issue, an NPE in findExecutableOnPath. Check out #3170 instead.
