Script works on Desktop, but not on Service. Says "unsupported conversion"

[matdardenne]

Hello,

I'm trying to use R to create a table with a single element where it displays the reverse geocoded address of a lat-lon position using Nominatim.

It works fine on the desktop version:  

But it displays this error when I publish it to the web:

This is the code I am using, nothing fancy:

library(gridExtra)
library(httr)

lat <- dataset$latitude
lon <- dataset$longitude

x <- c("http://nominatim.openstreetmap.org/reverse?format=json&lat=", lat, "&lon=", lon)
request_url <- paste(x, collapse="")

r <- GET(request_url)
r <- content(r)

address <- r$address

t <- data.frame(
    Rua=c(address$road),
    Cidade=c(address$city),
    UF=c(address$state)
)

grid.table(t)

What could be causing this issue "Error in iconv(x, "latin1", "ASCII") : unsupported conversion from 'latin1' to 'ASCII' in codepage 1252"? I researched it around the web, but found nothing that could give me a hint on what to do.

Please know that I am very new both to Power BI and R, so if anyone can lend me a hand, try to be very specific.

@matdardenne There are only certain packages that are supported in the Service, see here for which one's. I'm not really familiar with this area, but it looks like the httr library isn't supported.

Trully the httr package is not mentioned in the supported packages list. It is hopeless then, I guess.

Thanks anyway for your quick reply.

At the moment HTTR is listed as a supported library, however I still get the same error as the OP.
