Error deploy shiny app - Error in value[3L] : invalid multibyte string at '<80>3.5 b<69>llion' Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> Execution halted

Hi, i'm new in R Shiny and I would like deploy a web application but I have some error and I don't understand why. My app run without any problem on an external browser. So when i want to deploy my app I have this message ;

Someone have an idea for how I can solve that?

What is the output of sessionInfo()?
What is nature of the shape file you are loading with GDAL? That is, what is its encoding?

For sessionInfo() I have that :

For the shape file, It's an extract of a klm file and I don't know what is the encoding... I don't found that in the properties sorry...

I had add encoding = 'UTF-8' for when I download all files for my apps but I had the same output. And I saved my app in UTF-8 but it's again the same

benderj · June 8, 2018, 1:17pm

For more information, I call all files via DropBox with this function :

dl_from_dropbox <- function(x, key) {
  require(RCurl)
  bin <- getBinaryURL(paste0("https://dl.dropboxusercontent.com/s/", key, "/", x),
                      ssl.verifypeer = FALSE)
  con <- file(x, open = "wb")
  writeBin(bin, con)
  close(con)
  message(noquote(paste(x, "read into", getwd())))                        
}

So for my shape file I used like that :

if (!file.exists("WSEAZonesAndExchangeBoundaries.zip")) {
dl_from_dropbox("WSEAZonesAndExchangeBoundaries.zip", "ievvw3a???????")
unzip(zipfile="WSEAZonesAndExchangeBoundaries.zip", overwrite=TRUE)
}
dta <- rgdal::readOGR(dsn = "WSEAZonesAndExchangeBoundaries",layer="Eircom-Exchange-Boundaries", stringsAsFactors=FALSE,encoding = 'UTF-8')

When I run sessionInfo() I get a more full description of my locale:

locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

Do you happen to have access to a Linux or Mac to try your application out on?

benderj · June 8, 2018, 1:43pm

Sorry I don't used the good pack for sessionInfo(), so I have that :

locale:
[1] LC_COLLATE=English_Ireland.1252  LC_CTYPE=English_Ireland.1252   
[3] LC_MONETARY=English_Ireland.1252 LC_NUMERIC=C                    
[5] LC_TIME=English_Ireland.1252

How can I change that?

No I'm on Windows 8, but when I run my app external (Internet Explorer) all is OK.. so I don't understand why

josh · June 8, 2018, 2:14pm

So shinyapps.io attempts to replicate what you have locally (except the operating system).

We capture the version of R, and the version of packages, and the locale.

I suspect that Windows is more lenient about running in a non-UTF-8 locale and loading a UTF-8 file than Linux.

The locale that shinyapps.io is logged, and you should be able to see it with rsconnect::showLogs():

benderj · June 8, 2018, 2:26pm

So I have that :

I need to change my local session to UTF8???

josh · June 8, 2018, 2:41pm

Not sure that changing your local locale to UTF-8 would do anything remotely.

But I would suggest either testing locally on a Linux based system, or digging into the shapefile to see if you can isolate that string.

benderj · June 8, 2018, 3:55pm

thanks for all !!
But I'm really new on r and I don't how can run that on a Linux based system
