the method "helper.api.stix_cyber_observable.read" in the connector.

Hi, I want to write my own connector, but I'm faced with the problem of getting data from the platform. I am trying to get only observable with type "ipv4-addr" as follows:

    _val = ["ipv4-addr"]
    opencti_entity = self.helper.api.stix_cyber_observable.read(
        filters={
            "mode":"and",
            "filters":[{
                "key":"type",
                "mode":"or",
                "values":_val
            }],
            "filterGroups":[],
        }
    )  

but there is no result, only None. I tried to set other keys, but I get an error:
{'name': 'UNSUPPORTED_ERROR', 'message': 'incorrect filter keys not existing in any schema definition'}

What don't I understand? I will be grateful for any help.

Hi @Jijach,
To filter on the entity type, use the key "entity_type" and to get all the observables corresponding to your filter, use list():

observables = opencti_api_client.stix_cyber_observable.list(
    filters={
        "mode":"and",
        "filters":[{
            "key":"entity_type",
            "mode":"or",
            "operator": "eq",
            "values":["IPv4-Addr"]
        }],
        "filterGroups":[],
    }
)
