I have problem get VegaLite.Export.to_svg()
to run in a docker container. The image is based on a tweaked Dockerfile generated with mix phx.gen.release --docker
, like this:
# Find eligible builder and runner images on Docker Hub. We use Ubuntu/Debian
# instead of Alpine to avoid DNS resolution issues in production.
#
# https://hub.docker.com/r/hexpm/elixir/tags?page=1&name=ubuntu

#
# This file is based on these images:
#
# - https://hub.docker.com/r/hexpm/elixir/tags - for the build image
# - https://hub.docker.com/_/debian?tab=tags&page=1&name=bullseye-20210902-slim - for the release image
# - https://pkgs.org/ - resource for finding needed packages
# - Ex: hexpm/elixir:1.14.1-erlang-23.3.4.4-debian-bullseye-20210902-slim

Someone knows how to fix this issue?
It looks like it does not find the actual node executable or so?
Thanks for help!
