Disabling CH not allowed on the server-side?

Maybe I should open another post, I’m having some troubles with the POST request, is there any document explaining the format?

curl -i -X POST -H 'Content-Type: application/json' -d '{"request": { "points" : [[11.248630, 46.030340], [11.265450, 46.325830] ] }, "model": { "base":"car"} }' http://localhost:8989/flex

{"message":"No path found due to maximum nodes exceeded 1000000","hints":[{"message":"No path found due to maximum nodes exceeded 1000000","details":"java.lang.IllegalArgumentException"}]}

Same thing if I try something more elaborated as in the java example linked above:

{
	"request": {
		"points": [
			[11.248630, 46.030340],
			[11.265450, 46.325830]
		]
	},
	"model": {
		"base": "car",
		"no_access": {
			"road_class": ["steps"]
		}
	}
}

note the GET query for same areas works:
