[NTG-context] selecting font by (file) name

Dear list, I have the following sample: \definefontfamily [mainface] [rm] [TeX Gyre Pagella] \definefontfamily [mainface] [tt] %~ [file:lmmonoproplt10-regular.otf] [name:lmmonoproplt10regular] \setupbodyfont [mainface] \starttext \type{monospace font} \stoptext Either by file or name, I’m not able to select the font. I get the following list from mtxrunjit: $ mtxrunjit --script font --list --file --pattern=lmmonoproplt10regular latinmodernmonoproplight light normal normal normal lmmonoproplt10regular lmmonoproplt10-regular.otf What am I doing wrong here?
