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.servicePath:

}, orderby:

} - 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?

Best Regards,
