Not able to deploy crowdsale

Question

when i am doing truffle migrate.i am able to deploy my crowdsale contract but my token contract is getting deployed but not the crowdsale contract.

var Sportist = artifacts.require("./Sportist.sol");
var SportistCrowdsale = artifacts.require("./SportistCrowdsale.sol");


module.exports = async function (deployer) {
    let rate = 1;
    let wallet = "0x300c7b7198a772C2154e4f2a47C0d89407a95A8A";
    let token;
    let openingTime = Math.floor((new Date()).getTime()/1000);
    let closingTime = openingTime + 1 * 60 * 60 * 24;
    let cap = 500000;
    let goal = 50000;
    let tokenWallet = "0x300c7b7198a772C2154e4f2a47C0d89407a95A8A";

let a  = await deployer.deploy(Sportist, "Sportist", "S", 6, 2000000000)
 console.log("asdasdasdasdasdasdasdasdasdasd");
token = await Sportist.deployed().then(instance=>instance.address)



await deployer.deploy(SportistCrowdsale,
    rate, wallet, token,
    openingTime, closingTime,
    cap,
    goal,
    tokenWallet)

    const crowdsale = await DappTokenCrowdsale.deployed();


console.log("after deployement ");

};

in the console it is showing that

and the crowdsale contract is

import "./crowdsale/emission/StagedCrowsale.sol";

contract SportistCrowdsale is RefundableCrowdsale, CappedCrowdsale, PostDeliveryCrowdsale, AllowanceCrowdsale, StagedCrowsale {
    constructor(
        uint256 rate, address wallet, IERC20 token,
        uint256 openingTime, uint256 closingTime,
        uint cap,
        uint256 goal,
        address tokenWallet) 
        Crowdsale(rate, wallet, token)
        TimedCrowdsale(openingTime, closingTime)
        CappedCrowdsale(cap)
        RefundableCrowdsale(goal)
        AllowanceCrowdsale(tokenWallet)
        StagedCrowsale()
    public {}

    function() external payable {
        buyTokens(msg.sender);
    }
}

we can use async function in new truffle beta version.so i updating the truffle version you can easily use await. i updated to the new beta version of truffle
