Unable to apply object type 'identify' with id

Hi

I have a question regarding pjsip_wizard when a certain endpoint can’t be resolved.

I created a new endpoint in pjsip_wizard and I used a FQDN as host. When reloading pjsip, asterisk throws the following errors

    -- Reloading module 'res_pjsip.so' (Basic SIP resource)
[Mar  6 10:00:43] ERROR[660859]: netsock2.c:303 ast_sockaddr_resolve: getaddrinfo("sip.bla.com", "(null)", ...): Name or service not known

    -- Contact test/sip:sip.bla.com:5060 is now Unreachable.  RTT: 0.000 msec

Even if pjsip_wizard could not create all required objects, it created the endpoint

 Endpoint:  test                                                 Unavailable   0 of inf
        Aor:  test                                               0
      Contact:  test/sip:sip.bla.com:5060                  ffee23acfc Unavail         nan
  Transport:  transport-udp             udp      0    184  0.0.0.0:5070

When the domain becomes reachable, it is updated accordingly, but the identify is still missing and thus, incoming calls may not work.

 Endpoint:  test                                                 Not in use    0 of inf
        Aor:  test                                               0
      Contact:  test/sip:sip.bla.com:5060                  ffee23acfc Avail         1.101
  Transport:  transport-udp             udp      0    184  0.0.0.0:5070

When I reload again, it generates the identify object and everything is fine

 Endpoint:  test                                                 Not in use    0 of inf
        Aor:  test                                               0
      Contact:  test/sip:sip.bla.com:5060                  ffee23acfc Avail         0.790
  Transport:  transport-udp             udp      0    184  0.0.0.0:5070
   Identify:  test-identify/test
        Match: 127.0.0.1/32

I’m using Asterisk 20.12.0 and this is the snipped of the endpoint

[global_options](!)
type = wizard
endpoint/allow = !all
endpoint/allow = alaw
endpoint/allow = ulaw
endpoint/allow = gsm
endpoint/allow = speex
endpoint/allow = g726

endpoint/dtmf_mode = rfc4733
endpoint/fax_detect = yes
endpoint/identify_by = auth_username,ip
endpoint/language = en
endpoint/t38_udptl = yes
endpoint/t38_udptl_maxdatagram = 400
endpoint/t38_udptl_ec = redundancy
endpoint/timers = yes
endpoint/timers_min_se = 600
endpoint/timers_sess_expires = 3600
endpoint/direct_media = no
endpoint/tos_audio = ef
aor/remove_existing = yes
aor/remove_unavailable = yes
endpoint/allow_transfer = yes

[charact_trunk_standard](!)
type = wizard
aor/qualify_timeout = 2
aor/qualify_frequency = 60


[test](global_options,charact_trunk_standard)
transport = transport-udp
endpoint/context = sip-trunk-incoming-from-test
remote_hosts = sip.bla.com:5060
identify/match = sip.bla.com

My question is, is there a way to somehow detect a situation where objects are missing? Somehow over AMI? Or even better, would it be possible to generate the failed identify object as soon as the DNS resolution worked?

Thanks!
