[OTP 0.13] [Isochrones] java.lang.NullPointerException null

[Karimou Ba]

Hello,

I am trying to use OTP (version 0.13) to get some isochrones but I keep on receiving the above message: java.lang.NullPointerException. 

My request was: http://localhost:8080/otp/routers/default/isochrone?fromPlace=48.858,2.294&date=2015/03/03&time=12:00:00&mode=WALK&walkSpeed=3&maxWalkDistance=1000&precisionMeters=100&cutoffSec=3600

Reading the error logs it seems that the issue is coming from line 189 in the class org.opentripplanner.api.resource.Lisochrone (inside the computeIsochrone function) =>

"isochrones = otpServer.isoChroneSPTRenderer.getIsochrones(isoChroneRequest, sptRequest);" 

I am still really new to OTP (and Java...) so the issue is maybe obvious...apologies if so...

Has anyone ever encounter similar issue with Isochrones?

Cheers

Karimou

It's a known issue, caused by the change in the way we inject dependent
services. It has been solved in master in commit 90c898a6:
https://github.com/opentripplanner/OpenTripPlanner/commit/90c898a6a066c87bac64eeefb1a97ac7a288eabe

Attached is a patch backported to 0.13, also seen here:

Hi Laurent,

is it possible to apply that path to the master (1.0.0.SNAPSHOT)?     Andrew suggested us to use the most recent version to fix some itinerary problems (link below),  but the isochrone are no longer working.    It seems that the patch has not been apply to the master.

Can it be fixed?

This patch is a backport *from* master, so it should be definitively on master.

But what in the isochrone is not working exactly?

Ok, we are currently running many version at the same time trying to sort things out and we got confused a liitle bit. 

1- I was wrong about the patch, it is ok on master.

2- We finally figure out that what did change  between 0.13  and master is the isochrone format.

Using that local URL :

http://132.207.98.170:8014/otp/routers/default/isochrone?fromPlace=45.537854,-73.611638&date=2015/03/20&time=11:00:00&maxWalkDistance=500&mode=WALK,TRANSIT&cutoffSec=300&cutoffSec=600&cutoffSec=900&cutoffSec=1200&cutoffSec=1500&cutoffSec=1800&cutoffSec=2100&cutoffSec=2400&cutoffSec=2700&cutoffSec=3000&cutoffSec=3300&cutoffSec=3600

In 0.13 =>  GeoJSON is returned  => it's what our program is expecting
master => zip file is returned (shp) => our program crash.

Is there a way to force a GeoJSON format?

thank you!

Sure! You set your "Accept" HTTP header to "application/json". Using
curl for example:

curl --header "Accept: application/json"
"http://a.b.c.d/otp/routers/default/isochrone?..."
