<ERR> filters, line 1: Missing AS_PATH attribute

Hi,

In our BIRD 2.14 we’re running roa_check like this:

  if (net.type = NET_IP4) then {
    case roa_check(r4, net, bgp_path.last) {

However, the BIRD logs show the following error:

<ERR> filters, line 1: Missing AS_PATH attribute

would it be advisable to add a check to determine whether the route is a BGP route before proceeding?
