Hetzner has changed it's API and removed the field `datacenter` from the
primary IPs in favor of `location`. This change reflex this and adjusts
the configuration accordingly. Note, that this change didn't require any
manual state changes. Instead I applied the former plan with the newest
provider once. Hence the provider already treated the fields correctly I
only had to adjust the configuration.
Chapeau Hetzner for this good transition!
