appshot does not display graph on debian 11

Question

I try to use appshot to take an image from a shiny app. It works well on Windows, but not on my Debian server. If I try this:

  appdir <- system.file("examples", "01_hello", package = "shiny")
  appshot(appdir, "01_hello.png")

this gives this:

(without the graph)

My server is Debian 11.5 with:

• Shiny Server v1.5.18.987
• Node.js v16.14.0
• R version 4.2.1
• phantomjs install like this : https://gist.github.com/julionc/7476620.

If anyone can help me. Thanks a lot.

Answer 1

I install the 2.1.1 version of phantomjs.

Follow this https://gist.github.com/julionc/7476620 but replace 1.9.8 by 2.1.1.

It works !
