extracting pages using luacode

extracting pages using luacode

I'm trying to extract pages from an existing pdf using lua.
But this approach to extract pages 11 and 30 does not work:

\starttext
\startluacode
for i, blz in ipairs({11, 30}) do
  context.startTEXpage()
  context.externalfigure("my_pdf.pdf", page=blz)
  context.stopTEXpage()
end
\stopluacode
\stoptext


Where am I missing the point?
