Error invalid char in json text. about osrm

[rCarto]

Hello,
I see no problem.
Do you use the demo server or your own?

I tried using the demo server.

options(osrm.server = "https://router.project-osrm.org/", osrm.profile = "driving")

Hello,
Except from occasional "Too Many Request..." messages the function seems to work:

library(osrm)
#> Data: (c) OpenStreetMap contributors, ODbL 1.0 - http://www.openstreetmap.org/copyright
#> Routing: OSRM - http://project-osrm.org/
library(sp)
x <- osrmIsochrone(loc = c(-95.9345,41.2565), breaks = 10)
#> Linking to GEOS 3.7.1, GDAL 2.4.0, PROJ 5.2.0
plot(x)

Beside, I use options(osrm.server = "http://router.project-osrm.org/", osrm.profile = "driving"), http instead of https
