I have been trying to deploy a Shiny App on Shinyapps.io but always I have the same response:`ERROR: An error has occurred. Check your logs or contact the app author for clarification.` . At first, I tried it with my own app, but I give up and I though that my app had an error. Then I get a very simple app from internet that only have a few code lines and... surprise!, It didnt work. I don't know why, because I followed all the steps and I am seeing the app on my local window. So I checked relative paths, etc, and none were used. Logs neither help so I dont know what more to do. Please any advice could be useful. Many thanks

This is the R shiny code:

ui.R

library(shinydashboard)
library(rsconnect)

setwd(dirname(rstudioapi::getActiveDocumentContext()$path))
deployApp()
ui <- dashboardPage(
dashboardHeader(title = "Info boxes"),
dashboardSidebar(),
dashboardBody(
# infoBoxes with fill=FALSE
fluidRow(
# A static infoBox
infoBox("New Orders", 10 * 2, icon = icon("credit-card")),
# Dynamic infoBoxes
infoBoxOutput("progressBox"),
infoBoxOutput("approvalBox")
),

# infoBoxes with fill=TRUE
fluidRow(
infoBox("New Orders", 10 * 2, icon = icon("credit-card"), fill = TRUE),
infoBoxOutput("progressBox2"),
infoBoxOutput("approvalBox2")
),

fluidRow(
# Clicking this will increment the progress amount
box(width = 4, actionButton("count", "Increment progress"))
)
)
)

server.R

server <- function(input, output) {
output$progressBox <- renderInfoBox({
infoBox(
"Progress", paste0(25 + input$count, "%"), icon = icon("list"),
color = "purple"
)
})
output$approvalBox <- renderInfoBox({
infoBox(
"Approval", "80%", icon = icon("thumbs-up", lib = "glyphicon"),
color = "yellow"
)
})

# Same as above, but with fill=TRUE
output$progressBox2 <- renderInfoBox({
infoBox(
"Progress", paste0(25 + input$count, "%"), icon = icon("list"),
color = "purple", fill = TRUE
)
})
output$approvalBox2 <- renderInfoBox({
infoBox(
"Approval", "80%", icon = icon("thumbs-up", lib = "glyphicon"),
color = "yellow", fill = TRUE
)
})
}

This line is the problem:

setwd(dirname(rstudioapi::getActiveDocumentContext()$path))

a) You cannot change the working directory

b) the RStudio IDE is not running on shinyapps.io, so you cannot call rstudioapi

And there is another way to set the dir where the app is executed? Yo avoid innecesary execution time I created a var on first execution and save It and next times I load the file that its saved on the same path the script is. (not in this code, on the one I really want to publish)

Very thank you for your response. Ill check It when I can get a better conection than I am using right now.

You may not set the directory where the application is executed, but you may use relative paths to access files in your bundle.

There is currently no persistent storage for shinyapps.io (http://docs.rstudio.com/shinyapps.io/Storage.html), but it is something we will add in the future.

Hi Joshua,

I have been trying to deploy a Shiny App on Shinyapps.io but always I get the same error response as Victor - "An error has occurred. Check your logs or contact the app author for clarification". So i tried to run with a sample shiny code and tried to deploy it. See the code and the attached log info below. Please advise me on this issue. Thanks!

R Shiny code:

library(rsconnect)

library(shiny)

ui <- fluidPage(

titlePanel("Test Data"),

sidebarLayout(

sidebarPanel(

sliderInput("bins",

"Number of bins:",

min = 1,

max = 50,

value = 30)

),

mainPanel(

plotOutput("distPlot")

)

server <- function(input, output) {

output$distPlot <- renderPlot({

x <- faithful[, 2]

bins <- seq(min(x), max(x), length.out = input$bins + 1)

hist(x, breaks = bins, col = 'darkgray', border = 'white')

})

}

#shinyApp(ui = ui, server = server)

deployApp(appDir = "../Users/ajayaraman/Desktop/R map/test", appName = 'test', appTitle = "test_wrk")

I tried to use relative path instead of absolute paths, still its showing the setwd error. Also, i ran the code without using the setwd() function and yet it shows the same error. Is this due to some other issue? Please let me know on this.

Thanks!
