Qradar request returns "Success". but NO case created from offence #32

Using these versions:
Hive version=3.1.1
ES= 5.6.9

Qradar section
[QRadar]
server:192.168.10.199
auth_token:---*
cert_filepath:/home/Downloads/qradar.cer
api_version:8.0

Request to Qradar:
curl --header "Content-Type: application/json" --request POST --data '{"timerange":10000}' http://192.168.10.199/QRadar2alert

response:
{"offences": [], "succes:true"}

I have 4 offences at the moment in the Qradar web console.

What might possibly be the issue here?
