Please, ANSWER this question AT https://ask.fiware.org/question/597/cant-display-the-poi-from-contextbroker-to-mapviewer/

Question:
can't display the POI from ContextBroker to MapViewer

Description:
I'm trying to connect the OrionContextBroker and Wirecloud MapViewer widget in the local environment without the FIWARE Lab.
I want to display the POI from ContextBroker to MapViewer, but nothing appears in the map.

The following Entity is entered in the OrionContextBroker:

curl localhost:1026/v1/contextEntities/City1 -s -S --header 'Accept: application/json' | python -mjson.tool
{
"contextElement": {
"attributes": [

,

],
"id": "City1",
"isPattern": "false",
"type": "City"
},
"statusCode": {
"code": "200",
"reasonPhrase": "OK"
}

}

The configuration of the NGSISource operator is:

NGSI server URL : http://localhost:1026/

NGSI proxy URL : http://localhost:3000

Use the FIWARE credentials of the user : true

NGSI scope : /

NGSI entity types : City

Monitored NGSI Attributes : Latitud, Longitud

The configuration of the NGSI Entity To PoI operator is:

Coordinates attribute : Latitud, Longitud

NGSI source operator outputs the following error:

“Error creating subscription in the context broker server: Unexpected response from WireCloud's proxy”

And Browser Console outputs the followingerror:

http://localhost/cdp/http/localhost:1... Failed to load resource: the server responded with a status of 422 (Unknown Status Code)

I'm guessing that there is a cause to NGSIProxy.
Do you know something cause?
Please help me.
