[Fiware-tech-help] Assistance for errors

[Maria Tziakouri]

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?
