POST to /monitor/states with payload of {"choice": "bgp_prefixes"} does not return received routes

Calling the API over HTTP(S) with the following parameters does not return the list of routes received from any of the neighbours:

Method: "POST"
Path: "/monitor/states"
Payload: {"choice": "bgp_prefixes"}
Headers: {"content-type": "application/json"}

Example result:

{ 'choice': 'bgp_prefixes',
  'bgp_prefixes': [
        {'bgp_peer_name': 'some_ipv4_peer'},
        {'bgp_peer_name': 'some_ipv6_peer'}
    ]
}

I can see the routes being advertised by the neighbour in its out-RIB for the Ixia-c neighbour.
I tried filtering by peer name and address family, no prefixes returned. Tried with explicitly requesting a prefix using the filtering function as well, same result.

Interestingly it is also mentioned here:

5. Fetch BGP prefix announcements - TODO this doesn't show the actual announcements

curl -sk "${OTG_HOST}/monitor/states" \
    -X POST \
    -H  'Content-Type: application/json' \
    -d '{ "choice": "bgp_prefixes" }'
