Read link from external text file and include into hyperlinked image

Question

I would like to incorporate a link into a picture using \href. The links are stored in text files. The .tex file should be able to read form those text files (i.e. 1.text) and generate that clickable image.

I already got quite a good answer in this question How to add externally stored link text into a hyperlink?

...but I still have a problem:

% !TeX program = lualatex
\documentclass{article}%
\usepackage{graphicx}


\usepackage{hyperref,catchfile}% for the links
\usepackage{verbatim}% for the input

%To generate a text file for demonstration
\begin{filecontents*}{1.txt}
https://www.youtube.com/
\end{filecontents*}


\usepackage{hyperref,catchfile}
\newcommand\urlFromFile[1]{%
    \CatchFileDef\myurl{#1}{\catcode`\#=12\catcode`\%=12}%
    \expandafter\url\expandafter{\myurl}}

\begin{document}
    \href{\urlFromFile{1.txt}}{\includegraphics[width=\linewidth]{example-image}}
\end{document}
%

I get:

line 16: TeX capacity exceeded, sorry [parameter stack size=10000]. \href{\urlFromFile{1.txt}}
