[luatex] Example of error when using \xfrac

Hi,

I get an error when compiling the attached example file with LuaTeX on
an updated TL 2019 system. I also attach the log, which contains the
following error:

    ! Undefined control sequence.
    \GenericError  ...                                
                                                        #4  \errhelp \@err@     ...
    l.27238   }
             
    ? X

I don't know much about TeX (or LuaTeX), but the example file used to
compile on an older TL version. Is the example now invalid?

Best,

Scott
