I have the same error. I suppose there's an issue with BiocStyle.
After some debugging I found out that adding

\definecolor{fgcolor}{rgb}{0.345, 0.345, 0.345}
\newcommand{\hlsng}[1]{\textcolor[rgb]{0.192,0.494,0.8}{#1}}%
\newcommand{\hldef}[1]{\textcolor[rgb]{0.345,0.345,0.345}{#1}}%

right after the `BiocStyle::latex()` chunk fixes the issue.
