[NTG-context] lua-error when asking for the fontame

Hello, today I updated ConTeXt to the version of 2019-03-05. While testing a type-script I got an error, when I ask for the font name. lua error > lua error on line 1 in file /test.tex: ...ext/tex/texmf-context/tex/context/base/mkiv/font-syn.lua:519: bad argument #1 to 'lower' (string expected, got nil) MWE: \setupbodyfont[pagella,rm,12pt] \starttext This text is written in \font\fontname \stoptext
