Pandoc: Creating dynamic headers with Variables

In my preamble I use:

\usepackage[ngerman,english]{isodate}
\newcommand{\langMonth}{\month@ngerman}
$if(langDe)$
\renewcommand{\langMonth}{\month@ngerman}
$endif$
$if(langEn)$
\renewcommand{\langMonth}{\month@english}
$endif$

\usepackage{tikz}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\renewcommand{\headrulewidth}{0pt}
\fancyfoot[CO,CE]{\thepage}
%\setlength\headheight{100pt}

\rhead{\begin{tikzpicture}\node[above right, opacity=.5] { $if(Beschreibung)$$Beschreibung$$endif$ };  
\node[below right, opacity=.5]{\langMonth \, \the\year };
\end{tikzpicture}}

\lhead{\begin{tikzpicture}
\node[opacity=.5] {\includegraphics[width=0.25\textwidth]{images/Logo.png}};
\end{tikzpicture} }

With that I want basically two things: Write the month dependending on language, however with that, I get the LaTeX Error: Missing \begin{document}. The other thing I would like to have, is to set some description dynamically in the header, however the variable Beschreibung just gets ignored. I call pandoc by:

pandoc -o doc.pdf test.md --template mytemplate.latex --pdf-engine lualatex --verbose -V Beschreibung=dynamicDescription

Any suggestions? Thank you very much.

Instead of reinventing the wheel, you can use the babel and datetime2 package to automatically print the months in the language of your document.

\documentclass[ngerman]{book}

\usepackage{babel}
\usepackage[calc]{datetime2}

\usepackage{tikz}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\renewcommand{\headrulewidth}{0pt}
\fancyfoot[CO,CE]{\thepage}
\setlength\headheight{100pt}

\rhead{\begin{tikzpicture}
\node[below right, opacity=.5]{\DTMmonthname{\the\month}
 \, \the\year };
\end{tikzpicture}}

\lhead{\begin{tikzpicture}
\node[opacity=.5] {\includegraphics[width=0.25\textwidth]{example-image-duck}};
\end{tikzpicture} }


\begin{document}

test

\end{document}
