> +Question:+
> How to make exposed locally JSON data seen as Context Provider by FIWARE Orion Context Broker?
> +Description:+
> I think that I am doing everything alright, but I still cannot make JSON data exposed on my local server to be seen as Context Provider by FIWARE Orion Context Broker.
> SETUP
> I have whole Orion Context Broker all setup and running after following this commands:
> docker pull mongo:3.6
> docker pull fiware/orion
> docker network create fiware_default
> docker run -d --name=mongo-db --network=fiware_default \
>   --expose=27017 mongo:3.6 --bind_ip_all --smallfiles
> docker run -d --name fiware-orion -h orion --network=fiware_default \
>   -p 1026:1026  fiware/orion -dbhost mongo-db
> ENTITIES
> I also added one Store entity (from https://github.com/Fiware/tutorials.Getting-Started tutorial) by running:
>     curl -iX POST \
>   'http://localhost:1026/v2/entities' \
>   -H 'Content-Type: application/json' \
>   -d '
> {
>     "id": "urn:ngsi-ld:Store:001",
>     "type": "Store",
>     "address": {
>         "type": "PostalAddress",
>         "value": {
>             "streetAddress": "Bornholmer Straße 65",
>             "addressRegion": "Berlin",
>             "addressLocality": "Prenzlauer Berg",
>             "postalCode": "10439"
>         }
>     },
>     "location": {
>         "type": "geo:json",
>         "value": {
>              "type": "Point",
>              "coordinates": [13.3986, 52.5547]
>         }
>     },
>     "name": {
>         "type": "Text",
>         "value": "Bösebrücke Einkauf"
>     }
> }'
> Moreover I also successfully registered my Context Provider:
>     curl -iX POST   'http://localhost:1026/v2/registrations'   -H 'Content-Type: application/json'   -d '{
>   "description": "Temperature Provider",
>   "dataProvided": {
>     "entities": [
>       {         
>         "id": "urn:ngsi-ld:Store:001",
>         "type": "Store"
>       }                                             
>     ],                                
>     "attrs": [                                   
>       "temperature"
>     ]    
>   },
>   "provider": {
>     "http": {
>       "url": "http://localhost:8080/temperature"
>     },                       
>      "legacyForwarding": true
>   }      
> }'
> CONTEXT PROVIDER
> I exposed locally my Context Provider (exposed by my SpringBoot application written in Java 10) at http://localhost:8080/temperature. The JSON data (returned in html body) looks like that:
> {"contextResponses":[{"contextElement":{"attributes":[{"name":"temperature","type":"float","value":"16"}],"id":"urn:ngsi-ld:Store:001","isPattern":"false","type":"Store"},"statusCode":{"code":"200","reasonPhrase":"OK"}}]}
> PROBLEM
> When I try to get other entity's attributes (like name or location) it works fine, but when I try to get temperature attribute with this query:
> curl -X GET   'http://localhost:1026/v2/entities/urn:ngsi-ld:Store:001/attrs/temperature/value'
> I get the following error: 
> {"error":"NotFound","description":"The entity does not have such an attribute"}
> The only one error log in the Context Broker docker is:
> time=Thursday 06 Dec 15:29:37 2018.751Z | lvl=WARN | corr=N/A | trans=N/A | from=N/A | srv=N/A | subsrv=N/A | comp=Orion | op=postQueryContext.cpp[146]:queryForward | msg=Runtime Error (error forwarding 'Query' to providing application)
