Issues with entity creation in feature:linked-data branch

[YasinAl]

Dear developers,

I am trying to use the linked-data branch as I prefer to use NGSI-LD instead of V2.
I am trying to follow the turtleism example (which works in the V2 version) on this new branch but whenever I run the ros node I get the following error:

Could not create Entitiy /turtle1/pose in Contextbroker : {"error":"BadRequest","description":"entity id length: 0, min length supported: 1"}
Cannot update attributes in Contextbroker for topic: /turtle1/pose : {"error":"BadRequest","description":"entity id specified in payload"}

Does anyone have any idea as to what I am doing wrong?

Best regards,
Yasin
