Describe the problem in detail
Hello! I am encountering some issues in generating shiny apps that contain boxplots created by ggplot2. By running the example provided above, I get the following error:
Warning: Error in ggplot2::geom_boxplot: Problem while converting geom to grob.
i Error occurred in the 1st layer.
Caused by error:

Input to asJSON(keep_vec_names=TRUE) is a named vector. In a future version of jsonlite, this option will not be supported, and named vectors will be tra.
When I run the traceback() function, I get the following output
11: execCallbacks(timeoutSecs, all, loop$id)
10: run_now(timeoutMs/1000, all = FALSE)
9: service(timeout)

})

while (!.globals$stopped) {

}
}))

I should mention that this error occurs only on Windows, if I switch to linux, the app works just fine. Also, if I change geom_boxplot with geom_violin, the error disappears.
The plot-generating code works just fine outside the shiny reactive context.
Any help to solve this issue would be very much appreciated! Thank you!!
Experiencing the same issue, in Windows 11. I would appreciate any help with this issue. The versions of the packages I have are:
[1] "ggplot2 version: 4.0.0"
[1] "shiny version: 1.11.1"
I was able to successfully run this app locally
ui <- shiny::fluidPage(
shiny::h1("Test"),
shiny::plotOutput("boxplot")
)
server <- function(input, output, session) {
output$boxplot <- shiny::renderPlot({
df <- data.frame(timepoint = rep("tp0", 100), gene_expression = runif(100))
ggplot2::ggplot(
data = df,
ggplot2::aes(
x = timepoint,
y = gene_expression)
) + ggplot2::geom_boxplot()
})
}
shiny::shinyApp(ui = ui, server = server)
on a windows 11 machine
