[Tex/LaTex] Pdfpages not working – alternative/reason

coverspdfpages

Hey I wonder why includepdf / pdfpages is not working…

In the isolated case a file works perfectly fine:

\documentclass{tudelft-report}
\usepackage{pdfpages}

\begin{document}
\frontmatter
\title[Control, fuel and landing gears]{WP3 Wing subsystems}

\author{D06}
\affiliation{Technische Universiteit Delft}
\coverimage{cover/cover}
%\makecover

\mainmatter
\chapter{Schematic of parts} 
\label{app:schematic parts}
In this appendix a schematic view of all part positions and their shape is show. Table lists the reference values.
\clearpage
\includepdf[pages={1}]{graphs_tables_figures/schematic_parts.pdf}




\end{document}

But once I uncomment the command \makecover the pdfpages fails (showing just a blank page instead of the pdf). How can I find the bug in this? And/or is there another way to "scale" an image easily to the full page?

EDIT: looking through our "official" style file I find this as \makecover:

%% Define the options for the makecover command.
\define@boolkey{cover}{back}[true]{}
\define@boolkey{cover}{nospine}[true]{}

You need to specify a page colour before loading pdfpages. It does not matter what the colour is. See page 11 of pdfpages documentation for information about why you need to do this.

\documentclass{tudelft-report}
\pagecolor{green}
\usepackage{pdfpages}

\begin{document}
\frontmatter
\title[Control, fuel and landing gears]{WP3 Wing subsystems}

\author{D06}
\affiliation{Technische Universiteit Delft}
\coverimage{example-image-b}%cover/cover}
\makecover

\mainmatter
\chapter{Schematic of parts}
\label{app:schematic parts}
In this appendix a schematic view of all part positions and their shape is show. Table lists the reference values.
\clearpage
\includepdf[pages={1}]{example-image-a}%graphs_tables_figures/schematic_parts.pdf}


\end{document}

Obviously my output includes standard images as I don't have your PDFs but it shows the solution does, indeed, work with my choice of 'green':
