Error during latex code generation - but all files are generated

[donatoaz]

I am running into an issue where the rendered pdf contains the line Error during latex code generation.

The logs show:

java -Djava.awt.headless=true -jar /Users/donatoaz/Downloads/plantuml-1.2024.6.j
ar -charset UTF-8 -tlatex:nopreamble report-plantuml.txt
PlantUML did not generate anything. (./report-plantuml.latex)) [12]
(./sections/artifacts.tex [13]

When I run the java command manually no error comes up and I also do have all support files created:

> prototype-report git:(main) ✗ ls *-plantuml*                                                                                                                                                                                                                                                                   
report-plantuml.latex report-plantuml.tex   report-plantuml.txt

And If I create a simple tex file with just

\documentclass{report}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{plantuml}

\begin{document}

\chapter{Example UML Diagram}

Here is an example UML diagram generated by PlantUML:

\begin{figure}[h!]
    \centering
    \input{report-plantuml.tex}
    \caption{Example UML Diagram}
    \label{fig:uml}
\end{figure}

\end{document}

it does render:

How can I troubleshoot it?
