Sin combustible al ejecutar el contrato a través de web3 js

Tengo problemas para invocar el contrato a través de web 3 js en el navegador. Estoy usando el desarrollo de trufas y migré y ejecuté pruebas con éxito.

También obtengo la información cuando consola.log the contract.at();

eventHost.createEvent("testevent1",5,30);

cuando ejecuto lo anterior en la consola de Chrome

  web3.min.js:2 Uncaught Error: VM Exception while processing transaction: out of gas
        at Object.InvalidResponse (web3.min.js:1)
        at s.send (web3.min.js:2)
        at r.e [as sendTransaction] (web3.min.js:2)
        at c.sendTransaction (web3.min.js:2)
        at c.execute (web3.min.js:2)
        at <anonymous>:1:11

entiendo esto

mi contrato Event.sol

contract Event {

    uint32 currentMaxNumOfEvents=0;
    struct eventDetail{
    uint32  eventId;
    address  eventHost;
    string  eventName;
    uint32  noOfDaysToRegsiter;
    uint32  maxMembers;
    address[]  memberAddress;
    }
    mapping(uint32 => eventDetail) public events;
    function joinEvent(uint32 selectedEventId)public returns (uint32){
         for (uint i = 0; i<events[selectedEventId].memberAddress.length; i++) {
             assert(events[selectedEventId].memberAddress[i]==msg.sender);
        }
        require(selectedEventId>=0&&selectedEventId<=currentMaxNumOfEvents);
        require(events[selectedEventId].memberAddress.length < events[selectedEventId].maxMembers);
        events[selectedEventId].memberAddress.push(msg.sender);
        return selectedEventId;
    }
    function createEvent(string eventName,uint32 noOfdays,uint32 maxMembers) public returns (uint32){
        events[currentMaxNumOfEvents].eventId= currentMaxNumOfEvents;
        events[currentMaxNumOfEvents].eventHost =msg.sender;
        events[currentMaxNumOfEvents].eventName = eventName;
        events[currentMaxNumOfEvents].noOfDaysToRegsiter = noOfdays;
        events[currentMaxNumOfEvents].maxMembers = maxMembers;
        currentMaxNumOfEvents += 1;
        return events[currentMaxNumOfEvents].eventId;


    }
}

mi script ejecutándose en el navegador

 if (typeof web3 !== 'undefined') {
            web3 = new Web3(web3.currentProvider);
        } else {
            // set the provider you want from Web3.providers
            web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:9545"));
        }
        web3.eth.defaultAccount = web3.eth.accounts[0];
        var contract = web3.eth.contract([{"constant":true,"inputs":[{"name":"","type":"uint32"}],"name":"events","outputs":[{"name":"eventId","type":"uint32"},{"name":"eventHost","type":"address"},{"name":"eventName","type":"string"},{"name":"noOfDaysToRegsiter","type":"uint32"},{"name":"maxMembers","type":"uint32"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"selectedEventId","type":"uint32"}],"name":"joinEvent","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"eventName","type":"string"},{"name":"noOfdays","type":"uint32"},{"name":"maxMembers","type":"uint32"}],"name":"createEvent","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"nonpayable","type":"function"}]);
        var eventHost = contract.at('0x345ca3e014aaf5dca488057592ee47305d9b3e10');
        console.log(eventHost);
