error:Host is not in this zone

[jeffwang8001]

I'm using dyn-rb, and could not add record with

dyn.a.fqdn("test.exmaple.net.").ttl(3600).address("1.1.1.1").save(:replace)
puts dyn.zone.publish

it reports:
/lib/dyn/traffic.rb:230:in `parse_response': Request failed: ERROR NOT_FOUND BLL - id: You did not reference a specific record (Dyn::Exceptions::RequestFailed)
INFO BLL - update: No record updated
