Hi Lorenzo,
I think this is related to an outdated version. Please could you download the latest version and replace the ngsi9.war with the new one.

...Let me know what happens.

Best regards,

Dear Tarek,

Can you please take care of this as GE owner?

Thanks,

Miguel

I'm Lorenzo Trisolini, student at University of Pisa, and I deployed an instance of the IoT-Discovery4.2 (http://catalogue.fiware.org/enablers/iot-discovery/downloads) taken from the fiware catalogue page.
I have a problem when i do GET http://localhost:8080/ngsi9/contextEntities/Room1 on the IOT-Discovery GE. The context Entitiy Room1 doesn't exist. Instead of receiving the messagge:

<?xml version="1.0" encoding="UTF-8"?><discoverContextAvailabilityResponse>
<contextRegistrationResponseList/>
<errorCode>
<code>404</code>
<reasonPhrase>Context Element Not Found</reasonPhrase>
<details xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string"/>
</errorCode>
</discoverContextAvailabilityResponse>

I don't receive any message and the log of tomcat server shows a
sequence of error messages relative to the IOT-Discovery.
I attach the text file with the log of tomcat server(logcatTomcat).
Let me say that this two lines in the log are the main ones to understand what is the error
CO_1: GET INDIVIDUAL CONTEXT ENTITY: eId = ''Room1
get context entity error: null

Instead the version 4.1 works if i do the same trial, despite the log of tomcat server
shows the same error lines of the previous case:
CO_1: GET INDIVIDUAL CONTEXT ENTITY: eId = ''Room1
get context entity error: null
I attach the text file with the log of tomcat server(logcatTomcat4.1).
