preload error: there is no package called 'shiny'

[atomes-epar]

The compiled app works using the httpuv::runStaticServer function, but it breaks when uploaded to a WordPress site. Full console output below.

I've experimented with the headers and this is what I get when I use COOP set to "same-origin" and nothing else. The app is just a toy example and its only functions are to create a slider input, read a CSV from the app directory, and display the contents in a DataTable.

App Code:

library(shiny)
library(DT)

libtable <- read.csv("papers.csv")

ui <- fluidPage(

    # Application title
    titlePanel("Title"),

    sidebarLayout(
        sidebarPanel(
            sliderInput("pubyear",
                        "Publication Year:",
                        min = 1965,
                        max = 2025,
                        value = 2021,
                        sep="")
        ),

        mainPanel(
           DTOutput("dtab")
        )
    )
)
server <- function(input, output, session) {
  
    output$dtab <- renderDataTable(libtable,extensions='SearchBuilder', options=list(dom='Qftp'), filter=list(position='top', clear=F))
}

# Run the application 
shinyApp(ui = ui, server = server)
