[luatex] LuaLaTeX + FanycyHdr issue

[jung.jinki at gmail.com]

Hello LuaTeX users,

I am trying to implement dynamic FanyHdr in Lua.
There is an odd error I am getting as follow :
(/Volumes/program/usr_local/texlive/2018/texmf-dist/tex/generic/oberdiek/gettit
      lestring.sty)) (./fancy_lua.out) (./fancy_lua.out)
     ABD: EverySelectfont initializing macros ABD: EveryShipout 
initializing macros
     ! Undefined control sequence.
     <argument> \undefinedpagestyle
     l.30 \pagestyle{mystyleeight}
     ?
Since macro version is working, I was expecting no error in Lua.
I need your help one this.

Regards,
onionsjk
