[xtruthx]

The error raises during creating a acknowledge-problem with comment and setting stickyness with false or true.

[root@server scripts]# curl -k -s -X "POST" "https://localhost:5665/v1/actions/acknowledge-problem" -H "Accept: application/json" -H "Content-Type: application/json; charset=utf-8" -u user:$(cat /etc/icinga2/.apipw.conf) -d "{\"type\":\"Service\",\"filter\":\"host.name==\\\"servername\\\"&&service.name==\\\"timesync\\\"\",\"author\":\"itsmscript\",\"comment\":\"INC000002462799\",\"sticky\":\"false\"}" 

{
    "results": [
        {
            "code": 500.0,
            "status": "Action execution failed: 'Error: Can't convert 'false' to a floating point number.\n'."
        }
    ]
}

    "results": [
        {
            "code": 200.0,
            "status": "Successfully acknowledged problem for object 'servername!timesync'."
        }
    ]
}

Expected Behavior

That you are able to use True or False for the action option "sticky" as value and it will be converted/accepted.

Current Behavior

The API is not converting false or true and expect a floating number.

The sticky argument is documented as being a boolean value. This implies that the JSON value you specify has to be either true or false, or (for HTTP arguments) a numeric value.
