The control sequence at the end of the top line
of your error message was never \def'ed. If you have

It would be nice to fix our GH Actions workflow. Has anyone seen
this before/have suggestions for where to start looking for problems?
Are you sure this is coming from a vignette? It looks like it would be
from an Rd file or DESCRIPTION:
The \Rhref macro is defined in Rd.sty. There's a LaTeX \doi macro in
jss.cls, but it doesn't use \Rhref. On the other hand, the automatic
conversion of the DESCRIPTION file uses it in the
tools:::.DESCRIPTION_to_latex function.
I think this comes from the glmmTMB vignette doing
print(citation("glmmTMB"),style="latex")
which produces LaTeX code via Rd2latex(). This uses Rd's \Rhref,
wrapping either \href from hyperref.sty, or, as a fallback, \url from
url.sty. In addition, the default tools::bibstyle() will also output the
volume number in \bold, another LaTeX command from Rd.sty.
I can see the vignette already accounts for \bold via
%% need this for output of citation() below ...
\newcommand{\bold}[1]{\textbf{#1}}
To fix the missing \Rhref definition you could similarly do
\NewCommandCopy\Rhref\href
after including hyperref (\NewCommandCopy needs LaTeX >= 2020-10-01).
Best,
Sebastian
