Hi, the latest update may have introduced problems for xml processing : For a document I could convert with version 2021.10.24 21:45 without problems gives me now this error : %%%%%%%%%%%%%%%%%%%%%%%%% ... structure > sectioning > title @ level 2 : 0.0 -> \documentvariable {title} fatal lua error: registered function call [929]: ...ext/tex/texmf-context/tex/context/base/mkiv/scrn-ref.lua:31: attempt to call a nil value (upvalue 'expandcurrent') stack traceback: ...ext/tex/texmf-context/tex/context/base/mkiv/scrn-ref.lua:31: in function <...ext/tex/texmf-context/tex/context/base/mkiv/scrn-ref.lua:27> (...tail calls...) mtx-context | fatal error: return code: 1 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Not sure what is going wrong. Any hints how I can start debugging? Any ideas what could have caused that change? (Ok, let's build a MWE..) Best, Denis
