GoBGP doesn't accept local prefixes if no import-policy-list is set

[XioNoX]

Running GoBGP 2.12.

If I have:

[global.apply-policy.config]
default-import-policy = "reject-route"
default-export-policy = "accept-route"

And try to add a local prefix: gobgp global rib -a ipv4-flowspec add match destination 192.0.2.1/32 then discard It's not being accepted: gobgp global rib -a ipv4-flowspec returns: Network not in table

But if change the configuration to:

[[defined-sets.neighbor-sets]]
  neighbor-set-name = "ns-all"
  neighbor-info-list = []
[[policy-definitions]]
  name = "reject-all-neighbors"
  [[policy-definitions.statements]]
    [policy-definitions.statements.conditions.match-neighbor-set]
      neighbor-set = "ns1"
    [policy-definitions.statements.actions]
      route-disposition = "reject-route"

[global.apply-policy.config]
import-policy-list = ["reject-all-neighbors"]
default-import-policy = "reject-route"
default-export-policy = "accept-route"

Which should have the same end results as there are only reject-route for imports. But in this case: gobgp global rib -a ipv4-flowspec add match destination 192.0.2.1/32 then discard gobgp global rib -a ipv4-flowspec It works:

   Network                     Next Hop             AS_PATH              Age        Attrs
*> [destination: 192.0.2.1/32] fictitious                                00:00:05   [{Origin: ?} {Extcomms: [discard]}]

As a side note, changing the policy to a accept-route it works as well.
