Shiny Update Windows 10 : Failed to load resource img src from local - r

Question

I'm working on a windows 10 with local R/RStudio installed.
A few days again I updated R to v3.5.3 and RStudio to v1.2.1330.
I didn't check my app immediately, only a few days later. Meanwhile I had to install many Julia/Atom-Juno packages for a training and now when I run (locally) an app I'm working on, all the images are gone.
https://github.com/phileas-condemine/carto_indicateurs
The app looked like that : https://drees.shinyapps.io/Cartographie_des_indicateurs/ (I didn't try to redeploy, even if, being another OS it might still work)
Here is a simple reprex
within app.R (ran within an RStudio project)
library(shiny)
download.file(url = "https://www.rstudio.com/wp-content/uploads/2019/03/RStudio-Logo-Blue-Gray-125.png",
destfile = "www/rstudio.png",mode = "wb")#I have to add this for windows 10
shinyApp(
ui = fluidPage(
tags$img(src="https://www.rstudio.com/wp-content/uploads/2019/03/RStudio-Logo-Blue-Gray-125.png"),
tags$img(src="rstudio.png")
),
server = function(input, output) { }
)
The LOCAL image doesn't render, instead I have a broken image. (the one I get from URL is OK)
When I open the Chrome inspector and check the JS console I have the following error
Failed to load resource: the server responded with a status of 404 (Not Found) rstudio.png:1
I tried to check the reprex with the latest rocker/rstudio image but I can't reproduce it. Probably because it's a Windows 10 related issue.
Here is my sessionInfo()

I tried re-installing R v3.5.3 & latest RStudio v1.2.1335, it doesn't fix it.
What troubles me most is that some of the apps render all the images without any problem.
For example this one works alright : https://github.com/phileas-condemine/trafic_dataviz.drees
Is it because of the dependencies that somehow fix it ?

Answer 1

Back to shiny 1.2.0 & R 3.5.2 fixes the problem, all images are displayed correctly. So the "bug" either comes from shiny 1.3.1 or R 3.5.3
