A very simple shiny app with upload feature is working locally but not on shinyapps.io
Code :
ui <- shiny::fluidPage(
fileInput("file", "Upload file")
)
server <- function(input, output){
}
shinyApp(ui, server)
Error occurring looks like this :

File to test on upload : http://www.mediafire.com/file/lh98smuid1mprxj/2018-05-20_02-00-10.mat/file
Have seen the following similar question ( Error deploying shiny app that uses fileInput to upload data ). But the solutions here does not work.
