java.lang.RuntimeException: JSON request faulty or incomplete #94

Hi,

Thanks for providing the solution. I have setup the map server (docker container) and the matcher server. however when running the test cases provided, I got error message saying '''java.lang.RuntimeException: JSON request faulty or incomplete''' The job submission I used is '''python util/submit/batch.py --host localhost --port 1234 --file src/test/resources/com/bmwcarit/barefoot/matcher/x0001-015.json''' The only thing I changed in the python batch.py is instead of using 'netcat' I used 'nc', as I got 'netcat: no such command' error. sample request message looks like this: "request": [{"time": "2014-09-10 06:54:07+0200", "id": "001", "point": "POINT(11.564388282625075 48.16350662940509)"}, {"time": "2014-09-10 06:54:22+0200", "id": "001", "point": "POINT(11.563678490482323 48.16198390379898)"},...] I wonder if it's because the 'time' is not in millisecond unix epoch time format? Could you please help providing some hints on debugging?

Thank you very much!

That could result from a different behavior of netcat such that it doesn't close the connection by default: Could you please try adding -q 0 so instead of netcat you use nc -q 0 in the batch script? If that doesn't help let me know and I will check it out in more detail.

Hi Sebastian thanks for getting back to me. Unfortunately that didn't work either. I've also tried something from the netcat cheatsheet on pushing file to listener port https://www.sans.org/security-resources/sec560/netcat_cheat_sheet_v1.pdf but that didn't work either. I setup the server on an AWS ec2 Linux instance. Do you have experience with this particular settings?

Thanks

I've tried to modify the test sample data by including only a few points, but I still get the same error:

TrackerServer: JSON request faulty or incomplete: {"format": "geojson", "request": [{"id": "x001", "time": 1410324847000, "point": "POINT (11.564388282625075 48.16350662940509)"}]} java.lang.RuntimeException: JSON request faulty or incomplete: {"format": "geojson", "request": [{"id": "x001", "time": 1410324847000, "point": "POINT (11.564388282625075 48.16350662940509)"}]}

can it be something with JSON parsing?

my fault, I was running the wrong server. nc localhost 1234 works for me now. I'll close the issue.
