[Fiware-tech-help] Assistance for errors

[Maria Tziakouri]

Hello, 

For both cases, I am using the Orion Context Broker global instance in FIWARE Lab (orion.lab.fiware.org:1026) so I believe that something is not right with that. I have nothing to do with the invalid characters in the data. 
Can you please check if Orion Context Broker global instance in FIWARE Lab is working as expected and let me know? 
Looking forward for your response!

Hi, 

Regarding your second point (related to WireCloud and mashups), I guess you have an invalid character in the data of some entity (usually it is caused by a line break), and there is a known bug on Orion Context Broker which generates invalid JSON structures on receiving certain characters in entities (such as line breaks). 

Best regards,

Hello, 

I would like to ask help for the following two errors. 

1. I am following this tutorial https://fiware-orion.readthedocs.io/en/master/quick_start_guide/index.html but when I try any command to Orion Context Broker I receive this error: 

{ 
"error": "Internal Server Error", 
"description": "Database Error (collection: orion.entities - query(): { quer y: { $or: [ { _ id.id : \"urn:smartsantander:testbed:357\" } ], _id.servicePath: { $in: [ /^/.*/, null ] } }, orderby: { creDate: 1 } } - exception: socket except ion [CONNECT_ERROR] for localhost:27017 (127.0.0.1) failed)" 
} 

Attached you may find a screenshot of the error. 


2. I am trying to create a mashup on Fiware Lab and I receive the following error when I use the NGSI source operator. 


"Error creating subscription in the context broker server: The server returned an invalid json structure" 


Attached you may find a screenshot of the error and a screenshot of the NGSI source operator settings. 


Can you assist me how can I resolve these problems please?
