Errors "File `foo_0' not found." and "Unknown keyword ("foo_0".eps)"

[magula]

When I'm trying to compile a simple graph plotting example from the documentation's gallery using asy -tex lualatex foo.asy, a log is printed, saying

This is LuaTeX, Version 1.10.0 (TeX Live 2019/Arch Linux)

! LaTeX Error: File `foo_0' not found.

When I'm using asy -tex latex foo.asy instead, a log is printed, saying

dvips: Unknown keyword ("foo_0".eps) in \special will be ignored
dvips: No \special psfile was given; figure will be blank

When I'm using asy -tex [pdflatex|tex] foo.asy, everything seems to work as expected.

The same happens for at least another example from the gallery (but not for all of them), but it's not limited to graphs -- e.g., the following will produce the same errors (but not if you remove any one of the last two lines):

pair P = (350.794, 102.062);
pair Q = (-P.y, P.x);

label(rotate(angle(P)/3.1415926*180)*Label("Lion King"), 68pt * unit(P) + 12pt * unit(Q), align = unit(P), darkgray);
clip(scale(7.5cm)*unitsquare);

I know that the last example worked fine until recently, so the issue seems to be pretty new.

Is it related to an issue on grffile (ho-tex/grffile#1) ?

[johncbowman]

Yes, this is likely related to the grffile file bug; you may need to update grffile as described in the above bug report. Make sure you are using the latest version (2.61 or later) of asy.
