Conflict

Andromeda answers 409 with the problem type https://uri.etsi.org/ngsi-ld/errors/Conflict. The request is well formed, but it clashes with the broker's current state. Unlike with AlreadyExists, nothing with the same identifier exists. The two things just can't stand side by side. The specification defines this type but gives it no status, so Andromeda answers 409, the same as AlreadyExists.

When this comes back

A context source registration gets this answer when it overlaps what the broker already serves, in one of two ways.

• An exclusive or redirect registration whose footprint overlaps another proxied registration.
• A registration that covers context data the broker already holds locally, including the proxied footprint of an inclusive one.

Shrink the registration's information until it no longer overlaps, or delete the registration it clashes with. See Registrations and Federation.
