Hi, I am hoping to use Openrouteservice from R. What is the magic invocation to make this work? I have tried the following:

library(curl)  
library(magrittr)  
new\_handle() %\>%  
handle\_setopt(copypostfields =  
“locations=[[9.70093,48.477473],[9.207916,49.153868]]”) %\>%  
handle\_setheaders(“Content-Type”=“application/json”,  
“charset”=“utf-8”,  
“Accept”=“application/json, application/geo+json, application/gpx+xml, img/png”,  
“charset”=“utf-8”,  
“Authorization”=“xxx”) %\>%  
curl\_fetch\_memory(url = “[https://api.openrouteservice.org/v2/matrix/driving-car](https://api.openrouteservice.org/v2/matrix/driving-car)”) %$% content %\>%  
rawToChar %\>% jsonlite::prettify()

But this returns error code 500 server error. What am I doing wrong?

Many thanks.
