Question:
FIWARE [NGSI] Orion-Cygnus-Hadoop HTTPBadRequestException: 'fiware-servicepath' through an Orion subscription

Description:
I want to persist some historical data from my server. So the documentation says that you must first send a subscription to Orion and then Orion will send the notification to Cygnus.

I made the subscription like this:

Entity payload = Entity.json("{\r\n" +
" \"entities\": [

],\r\n" +
" \"attributes\": [],\r\n" +
" \"reference\": \"http://192.168.10.3:5050/notify\",\r\n" +
" \"duration\": \"P4Y\",\r\n" +
" \"notifyConditions\": [

],\r\n" +
" \"throttling\": \"PT0.001S\"\r\n" +
"}");
Response response = client.target("http://192.168.10.3:1026/v1/subscribeContext")
.request(MediaType.APPLICATION_JSON_TYPE)
.post(payload);

And the creation of entities:

Entity payload = Entity.json("{ \"type\": \"Usuario\", \"id\": \"Usuario22\", \"temperature\":

, \"location\": { \"value\": \""latitud", "altitud"\", \"type\": \"geo:point\", \"metadata\": { \"crs\":

} }}");
Response response = client.target("http://192.168.10.3:1026/v2/entities")
.request(MediaType.APPLICATION_JSON_TYPE)
.post(payload);

Then, Cygnus log tell me:

HTTPBadRequestException: 'fiware-servicepath' header value does not match the number of notified context responses [...]

Do any of you know why this is happening? The creation of the headers should be done by Orion or, failing that, by using the configuration of the Cygnus...

Thank you in advance.
