Helvetica Text on PNG creation

[IantheFlyingHawaiian]

For some reason, when I'm creating an image from a drawio xml, the Helvetica font and bold font isn't being created on the docker-drawio-desktop-headless images.

Any ideas why?

Hello,

I try to reproduce the issue, but I can't. Maybe, I miss something.
I export a drawio file with the electron app and then with this docker image; the result is the same.

Command used

docker run -it -w /data \
      -v $(pwd):/data rlespinasse/drawio-desktop-headless \
      -x -o issue84-docker.png -f png issue84.drawio

Can you produce a test case file, and a PNG to highlight your issue?
