Query range via decisions API doesn't work

I can’t seem to work out how to query a range or CIDR via the API. Works with cscli ok:

# cscli decision list --range 88.87.84.0/24 --contained
╭─────────┬──────────┬─────────────────┬────────────────────────────┬────────┬─────────┬──────────────────────────────┬────────┬────────────┬──────────╮
│    ID   │  Source  │   Scope:Value   │           Reason           │ Action │ Country │              AS              │ Events │ expiration │ Alert ID │
├─────────┼──────────┼─────────────────┼────────────────────────────┼────────┼─────────┼──────────────────────────────┼────────┼────────────┼──────────┤
│ 2586050 │ crowdsec │ Ip:88.87.84.104 │ crowdsecurity/postfix-spam │ ban    │ RU      │ 39435 JSC ER-Telecom Holding │ 7      │ 2h41m25s   │ 21265    │
╰─────────┴──────────┴─────────────────┴────────────────────────────┴────────┴─────────┴──────────────────────────────┴────────┴────────────┴──────────╯

Single IP works fine:
$ curl -H “X-Api-Key: KEY” “http://localhost:8080/v1/decisions?range=88.87.84.104
[{“duration”:“2h56m44s”,“id”:2586050,“origin”:“crowdsec”,“scenario”:“crowdsecurity/postfix-spam”,“scope”:“Ip”,“type”:“ban”,“value”:“88.87.84.104”}]

These give no result (URLs removed due to new user posting links issue)
“v1/decisions?range=88.87.84.0/24”
“v1/decisions?range=88.87.84.0/24&contains=1”
“v1/decisions?scope=range&value=88.87.84.0/24”
“v1/decisions?scope=range&value=88.87.84.0/24&contains=1”

Any ideas?
