Incompatibility with fiware/orion:2.0.0 - fiware

Question

This is a question related with this issue
https://github.com/ging/fiware-cygnus/issues/6
I've deployed the iot stack with docker. These are the used containers:
fiware/orion:2.0.0
ging/fiware-cygnus:latest
ging/fiware-cygnus:latest
"Id": "sha256:b6baf1cbd18e6ba6ab5ec7d8e1d9c8a08bbc18b45037faa345e8465c890f454c",
"RepoTags": [ "ging/fiware-cygnus:latest" ],
"RepoDigests": [
"ging/fiware-cygnus#sha256:4fcf44666651ca63f1a74203bc12a7ffd9a1268f8d514dff1a83db269a1c6923"
],
"Created": "2018-10-17T15:52:19.749023834Z"
[And other containers not involved in the issue ...]
Currently the image fiware/orion:2.0.0 is sending the headers as follows.
--------------------------------------------------

--------------------------------------------------
Specifically, the header "Fiware-Servicepath" does not match what is expected this line of code. "fiware-servicepath," Fiware-ServicePath "," fiware-servicepath"
And this causes the following error:
`2018-10-31 12:15:41,201 ERROR [Timer-Driven Process Thread-1] o.a.nifi.processors.ngsi.NGSIToMongo NGSIToMongo[id=8f96c89d-850a-3578-b512-2b3f5f4fdacd] java.lang.NullPointerException
I think that it is caused by this line
String fiwareServicePath = (flowFile.getAttribute("fiware-servicepath")==null) ? flowFile.getAttribute("Fiware-ServicePath"):flowFile.getAttribute("fiware-servicepath");
