How can I add some error bar on a stacked bar pot?

Question

I'm trying to reproduce the following graph :

I've manage to get that but I don't know how to put the error bar :

Does anybody know how can I do that ?

There is my current code.

\documentclass[11pt]{report}
\usepackage{tikz,pgfplots,pgfplotstable}
\usepackage{lipsum}
\usepackage{xcolor}
\definecolor{bluereport}{RGB}{79, 129, 189}
\pgfplotsset{width=10cm, compat=1.9}
\begin{document}
\pgfplotstableread{
Label   A   B   C    D    err.A  err.B   err.C   err.D
OP1     17  51  97   85   1.65   19.52   57.11   32.48
OP2     18  84  129  54   1.65   19.52   57.11   32.48
OP3     20  49  208  119  1.65   19.52   57.11   32.48
    }\data
\begin{tikzpicture}
\begin{axis}[
    title style={align=center}, 
    title = {my title},
    ybar stacked,
    bar width=30pt,
    ytick={0, 60, 120, 180, 240, 300, 360, 420, 480},
    ymax=480,
    xtick=data,
    xticklabels from table={\data}{Label},
    ylabel={Time (min)},
    enlargelimits=0.15,
    tickwidth= 5pt,
    ymajorgrids=true,
    grid style=dashed,
    legend style={at={(0.5,-0.15)},
    legend style={/tikz/every even column/.append style={column sep=0.5cm}},
    anchor=north,
    legend columns=-1},
] 
\addplot [bluereport!90!black,fill=bluereport!100!white]    table[y=A, meta=Label, x expr=\coordindex] {\data};
\addlegendentry{A}
\addplot [bluereport!95!white,fill=bluereport!75!white] table[y=B, meta=Label, x expr=\coordindex] {\data};
\addlegendentry{B}
\addplot [bluereport!70!white,fill=bluereport!50!white] table[y=C, meta=Label, x expr=\coordindex] {\data};
\addlegendentry{C}
\addplot [bluereport!45!white,fill=bluereport!25!white] table[y=D, meta=Label, x expr=\coordindex] {\data};
\addlegendentry{D}
\end{axis}

\end{tikzpicture}
\end{document}

Thank you for your help.

Welcome! One needs to "unstack" the plots, for which one can use this solution, in order to add the error bars at the right vertical positions.

\documentclass[11pt]{report}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\definecolor{bluereport}{RGB}{79, 129, 189}
\pgfplotsset{width=10cm, compat=1.17}
\makeatletter% from https://tex.stackexchange.com/a/13665
\newcommand\resetstackedplots{%
\pgfplots@stacked@isfirstplottrue
}
\makeatother
\begin{document}
\pgfplotstableread{
Label   A   B   C    D    err.A  err.B   err.C   err.D

    }\data
\begin{tikzpicture}
\begin{axis}[
    title style={align=center}, 
    title = {my title},
    bar width=30pt,

    ymax=480,

    anchor=north,

]
\addplot [ybar stacked,bluereport!90!black,fill=bluereport!100!white]    table[y=A, meta=Label, x expr=\coordindex] {\data};
\addlegendentry{A}

\addlegendentry{D}
\resetstackedplots
\pgfplotsinvokeforeach{A,B,C,D}{
\addplot[forget plot,draw=none,stack plots=y,
     error bars/.cd, y dir=both, y explicit] 
    table[y=#1,  x expr=\coordindex,y error expr=\thisrow{err.#1}]
