I need to export my document. For this I use:

I have update my document with start and stop for chapter, section and

\useURL

  []
  [universally unique identifier]
and when I also have:
\from[UUID]

I get:

! LuaTeX error ...TeXt/tex/texmf-context/tex/context/base/back-exp.lua:328:
bad argument #2 to 'write' (string expected, got nil).

a real small test file is needed

This works:
\setupinteraction[
  color=blue,
  contrastcolor=red,
  focus=standard,
  state=start,
]

%\setupbackend[export=yes,xhtml=yes,css=yes]

\useURL
  [UUID]
  [http://en.wikipedia.org/wiki/Uuid]
  []
  [universally unique identifier]

\starttext

This new id is generated much like an \from[UUID]. The reason for the
change was that in this way a client number could be generated offline
and/or different databases could be merged without the risk that id's
would clash.

\stoptext

But when the \setupbackend is taken out of comment, it goes wrong.
