Actions on github including file from another directory

Question

On github I have a repository with a xelatex file which makes use of a font which is in a relative path going up in the tree in the repository:

\setmainfont[Path = ../fonts/fontin2_pc/,
    Extension = .ttf,
    BoldFont = Fontin-Bold,
    ItalicFont = Fontin-Italic,
    SmallCapsFont = Fontin-SmallCaps
]

and the actions is as follows:

name: Build LaTeX document
on: [push]
jobs:
  build_latex:
    runs-on: ubuntu-latest
    steps:
      - name: Set up Git repository
        uses: actions/checkout@v2
      - name: example-class-relations--svg
        uses: dante-ev/latex-action@latest
        with:
          root_file: en/cv.tex
          compiler: xelatex
          args: -interaction=nonstopmode -shell-escape

Now, locally this works fine, and the tex compiler finds the font without a problem. However, the action fails with a message that it cannot find the font(s). Is there something I am missing? The font files themselves are on the repo, just in a different path:
