still uncertain if osrm.profile = "walk" in osrmIsochrone works.

hi, similar topic may be discussed before.
To be able to use osrm.profile = "walk", I rebuilt the osrm instance using foot.lua. I did this after I finished building the default car.lua instance, which worked fine.
However, when I tried to build the instance using foot.lua in a totally new environment, I got an error
[error] Input file "/data/sweden-latest.osrm.ebg" not found!
I noticed this .ebg file was created in the previous step if using car.lua, but not foot.lua.
So I used car.lua first and then foot.lua later. It looked like the instance was built okay, and I can set osrm.profile = "walk" in options. But the results of osrmIsochrone was not reassuring. I gave two extreme time intervals to compare.

iso <- osrmIsochrone(loc,
                     breaks = seq(from = 0, to = 120, by = 60),
                     res = 400, returnclass = "sf")

and the results, according to my eyes, were very much similar, if not identical.
I guess .ebg file is where the problem is. Could anybody give some suggestions?
Thanks a lot.

Hello,
The problem seems related to your OSRM build and not to the R package. I think you should check/post issues here : https://github.com/Project-OSRM/osrm-backend/issues
