Hey amazing community!
I hope you're all doing great. 
I'm currently facing a bit of a roadblock with hosting RSelenium on shinyapps.io, and I'm reaching out to the brilliant minds here for some guidance.
The Challenge:
I've been working on a Shiny app that involves RSelenium for some web scraping magic. Locally, everything is smooth sailing, but when I try to host it on shinyapps.io, I encounter a pesky error that's causing a bit of a headache.
The Error:
Quarto not found.
[2023-12-03T09:48:08.811850540+0000] Execute script: packages/build/RSelenium.sh

Shiny Code:
library(shiny)
library(wdman)
library(RSelenium)
library(httr)
library(netstat)
ui <- fluidPage(
actionButton("btn", "Click Me!"),
textOutput("txt"),
)
server <- function(input, output, session) {
observeEvent(input$btn, {
#connect chrome driver
client_server <- rsDriver(
browser = "chrome",
chromever = "119.0.5735.90",
verbose = FALSE,
port = free_port(),
)
# connect remote driver to client
remDr <- client_server$client
remDr$navigate("http://www.google.com")
remDr$maxWindowSize()
title <- remDr$getTitle()
output$txt <- renderText(as.character(title))
# clean up
remDr$quit()
})
}
shinyApp(ui, server)
What I've Tried:
- Checked dependencies locally, and everything is installed.
- Used the latest version of RSelenium.
- Set up appropriate configurations for the Chrome driver.
