Hi---
I have a number of included figures that work in 20200920 but not in the cu= rrent 20210124 version. There's a project structure that sets everything up= but after that they are input as a figure:
\startplacefigure[title=3D{NS Hie= rarchy},
= ; reference=3D{f:ns-hierarchy}]
\input ns_hierarchy=
\stopplacefigure
and generate the error:

Continue, and I'll return the second argument (see above) as the result of = theoperation.

"boxrow.mp" is not in t= he same directory as the document but is in the configured through the usep= ath/usesubpath interface from an environment file.
I can put together and share a runnable MWE set of files if this informatio= n is not complete enough to identify the problem.
Here is the MWE that I used for the input figure file that demonstrates the= problem.
\defineMPinstance[ns_hier]
[
format=3Dmetafun,
extensions=3Dyes,
initializations=3Dyes,
method=3Ddouble,
]
\startMPinclusions{ns_hier}
input boxrow
\stopMPinclusions
\startMPdefinitions{ns_hier}
% nothing to see here....
\stopMPdefinitions
\startMPcode{ns_hier}
make_BoxRow
[
name =3D &qu= ot;Parent",
label =3D &qu= ot;Parent Root Namespace",
];
\stopMPcode

What if you put it in your tree? Someplace under

texmf-local/metapost/...

(run mtxrun --generate afterdpimng that)
