Question:
Fiware Context Provider hello world not working

Description:
Updated (II):
I'm trying to register a Context Provider as source for several KPIs.
So far, it seems registering might be working, as GET http://orion/v2/registrations returns something similar to what I set in creation:
{
// each registering a new id is returned: "id": "60991a887032541f4539a71d",
"description": "City Inhabitants",
"dataProvided": {
"entities": [

]
},
"provider": {
"http":

//, "legacyForwarding": false //perhaps there's a bug, cause although unset or set to false, broker still returns true.
}
}

However GET http://orion/v2/entities/city.inhabitants results in:
{
"error": "BadRequest",
"description": "Service not found. Check your URL as probably it is wrong."
}

GET http://orion/v2/entities?type=KeyPerformanceIndicator returns [] and context-provider is not being invoked any way.
I'm coding a nodejs application from scratch, to better understand what's going on https://github.com/FIWARE/tutorials.Context-Providers, and using tutorial containers as actual Fiware Broker, so all stores/shelf/products are working but not my KPI.
Any help would be much appreciated.
