Detailed ASPA_INVALID logging? (responsible AS and ASPA object)

[Christoph via Bird-users]

Hello,

we started to validate (logging only) ASPA objects with this:
if (aspa_check_downstream(at) = ASPA_INVALID) then
{
        print "ASPA INVALID announcement (monitoring only): ", net, " 
AS path: ", bgp_path;
}

Example output:

ASPA INVALID announcement: 91.223.183.0/24 AS path: (path 1764 5405 6830 
206659 197477 215563)

Then we manually investigate which AS along the path is responsible for 
the ASPA_INVALID result by asking routinator for the ASPA objects of all 
involved ASNs, example output for ASN6830 showing an AS0 ASPA:

"aspas": [
    { "customer": "AS6830", "providers": ["AS0"], "ta": "ripe" }
  ]

Depending on the length of the AS path this is cumbersome. Is there a 
way to write the first responsible AS and ASPA object to the log that 
caused the ASPA_INVALID result?

best regards,
Christoph
