I am running context minimals and Asymptote on Windows.This example used to work in the past, but it seems to have stopped working. Is there anything that has changed?

\usemodule[filter]

\defineexternalfilter

[ASY]

[filtercommand={asy -tex "context" -outformat pdf

-outname \externalfilteroutputfile},

output=\externalfilterbasefile.pdf,

cache=yes,

readcommand=\ReadImage,]

\define[1]\ReadImage{\externalfigure[#1]}

\starttext

Testing if we can include an asymptote image

\startplacefigure[location={here}, title={An Asymptote figure}]

\startASY

unitsize(1cm);

draw((-.1,0) -- (2,0), arrow=Arrow(TeXHead));

draw((0,-.1) -- (0,2), arrow=Arrow(TeXHead));

draw((0,0) .. (1,1) .. (2,sqrt(2)));

\stopASY

\stopplacefigure
