This is from
Take this example https://github.com/AlekseiBogachev/penguins-dashboard-docker using Quarto Shiny for Python interactive Dashboard.
# building
docker build -t penguins-dashboard .
# Running the container
docker run --rm -it -p 3838:3838 penguins-dashboard bash
Running shiny-server command and then going to http://localhost:3838/#plots I am seeing
An error has occurred
The application failed to start.
The application exited during initialization.
Looking at apps log inside the container we see
$ cat logs/penguins-dashboard-dockeruser-20240729-093421-46701.log
Error: lexical error: invalid char in json text.
NA

Removing penguins.qmd inside the docker container solves this, and I can see python is used
