I have this stacked ybar plot and having trouble to proper align the nodes near the coords. It works fine on all bar but the one with offset 65. I already tried \ifnum as @Jake suggested here: How can I move a single node in a tikz plot? This works, but throws me this error twice:

Extra \else. \end{axis}

When I add the \ifnum to my main document, I get even more of them. Any suggestions how to fix this, or why the label is missplaced in the first place?

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{filecontents}

\begin{filecontents*}{migration.tsv}
index   Kategorie   data    offset
5   five    1573    6
6   six 270 7
7   seven   497 65
\end{filecontents*}
\begin{document}

\begin{tikzpicture}
     \pgfplotstableread{migration.tsv}\migrationtable 
     \pgfplotsset{%
             width=\textwidth,
             height=.4\textheight,
             every tick label/.append style={font=\footnotesize}, %
             every node near coord/.append style={font=\footnotesize}, %
             compat=1.13%
                 }%
      \begin{axis}[%
          ybar stacked,
          scale only axis,
          x tick label style={rotate=45,anchor=north east}, 
          xtick=data,
          every node near coord/.append style={%
              anchor=south}
              ]
      \addplot[draw=black,fill=blue!50!white] table[x=index,y=data] from \migrationtable;
      \addplot[draw=black,fill=red,nodes near coords] table[x=index,y=offset] from \migrationtable;
      \legend{values,offset}
      \end{axis}
\end{tikzpicture}
\end{document}

This is the \ifnum block I used:

 every node near coord/.append style={%
       yshift={%
         \ifnum\coordindex=2 2ex\else 0pt\fi
       }%
 }

Also tried \newcommand{\equals}{=} to wrap the = as @egreg pointed out in question that can't find anymore.

I guess this is somehow similar to Center nodes near coords in a stacked ybar plot but I couldn't figure out how to use this to solve my problem. enter image description here

Remove this style option every node near coord/.append style={anchor=south}, and replace it with the following options:

nodes near coords align={anchor=south},
nodes near coords bar offset=1

Now, even if you increase the offset in your table by random amounts, the nodes will always appear nicely on top, without the need for you to manually shift them.

Output
