Question:
FIWARE Orion - Error: "Response to QueryContext is empty"

Description:
I have followed the NGSI API documentation and I'm using registrations to forward a query to a custom path which will handle it.

I'm working on the examples shown in the APIv2 Documentation. I have two containers running the Context broker on different ports.

In one of them I have created the Room1 asset, in the other I have created the registration for that asset.

I'm querying the second one for that identity, in the logs the following message appears:

orion2_1 | time=Friday 02 Nov 08:48:19 2018.704Z | lvl=WARN | corr=N/A | trans=N/A | from=N/A | srv=N/A | subsrv=N/A | comp=Orion | op=postQueryContext.cpp[168]:queryForward | msg=Other Error (context provider response to QueryContext is empty)

This is the registration:

{
"id": "5bdc14dfcbe7f9fb0a95002e",
"description": "Registration for Room1",
"dataProvided": {
"entities": [

],
"attrs": [
"temperature",
"pressure"
]
},
"provider": {
"http":

,
"supportedForwardingMode": "all",
"legacyForwarding": true
},
"status": "active"
}

This is the Room1 entity:

{
"id": "Room1",
"type": "Room",
"pressure": {
"type": "Integer",
"value": 720,
"metadata": {}
},
"temperature": {
"type": "Float",
"value": 23,
"metadata": {}
}
}

Can anyone help me?
