Vertical line causes 'dimension too large' error

Question

For the following plot (with time axis) I would like to add a bold, red vertical line at index 2010-01-01.

But I always run into a Dimension too large error. How can I solve this issue?

Here is the code

\begin{tikzpicture}
\begin{axis}[
    max space between ticks=25pt,
    scale only axis=true,
    every axis plot/.append style={very thick},
    tick style={black, thick},
    ylabel={},
    ymax=700000,
    %ymin=0,
    grid=major,
    enlarge x limits = false,
    width=\textwidth,
    height=0.5\textwidth,
    xticklabel = {\year},
    x tick label style={align=center},
    date coordinates in=x,
    table/col sep=comma,
    date ZERO={1991-01-01},
    xmin={1991-01-01},
    xmax={2021-01-01},
    xtick={1992-01-01, 1994-01-01, 1996-01-01, 1998-01-01, 2000-01-01, 2002-01-01, 2004-01-01, 2006-01-01, 2008-01-01, 2010-01-01, 2012-01-01, 2014-01-01, 2016-01-01, 2018-01-01, 2020-01-01},
    xticklabels={1992, 1994, 1996, 1998, 2000, 2002, 2004, 2006, 2008, 2010, 2012, 2014, 2016, 2018, 2020}
]
\addplot[black] table[x={month}, y={commits}, col sep=comma] {commits.csv};
\addplot[red, dashed] table[x={month}, y={0}, col sep=comma] {commits_growth.csv};
%\draw [red, dashed] ({2010-01-01}, 0) -- ({2010-01-01}, 700000); % causes 'Dimension too large' error
\end{axis}
\end{tikzpicture}
