Labels ref is rendered as `??`

[jmeinlschmidt]

While the \ref macro renders normally in Overleaf, I get ?? for all references in the resulting file when processing this action.

Examples:

\ref{analysis}

% ...

\section{Analysis and design}
\label{analysis}

Used configuration

      - name: Compile LaTeX document
        uses: dante-ev/latex-action@latest
        with:
          root_file: $TEXT_SRC.tex
          compiler: lualatex
          args: -lualatex -latexoption=-file-line-error -latexoption=-interaction=nonstopmode -shell-escape

Any ideas? Thank you!

You need to run lualatex twice to get labels rendered correctly. Reason: lualatex is a single-pass compiler and the reference was put before the label.
