Javascript Passport Google OAuth2需要在登录前注销

我正在尝试使用passport对google登录进行身份验证，但是，如果您在第一次进入页面时尝试登录，则会出现以下错误：

TokenError: Bad Request
   at Strategy.OAuth2Strategy.parseErrorResponse (/home/ubuntu/workspace/node_modules/passport-google-oauth/node_modules/passport-google-oauth20/node_modules/passport-oauth2/lib/strategy.js:329:12)

和我的passport配置：

var passport = require('passport');
var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;
var users = {};
exports.OAuth2Strategy = new GoogleStrategy({
    clientID:'ID',
    clientSecret:'secret',
    callbackURL: '/auth/google/callback',
    passReqToCallback: true
}, (req, accessToken, refreshToken, profile, done)=>{
    users[profile.id] = profile;
    done(null, profile);
});
passport.serializeUser((user, done)=>{
    done(null, user.id);
});
passport.deserializeUser((id, done)=>{
    done(null, users[id]);
});
exports.users = users;

任何帮助都将不胜感激，我只是一直在绕圈子

var passport = require('passport');
var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;
var users = {};
exports.OAuth2Strategy = new GoogleStrategy({
    clientID:'ID',
    clientSecret:'secret',
    callbackURL: '/auth/google/callback',
    passReqToCallback: true
}, (req, accessToken, refreshToken, profile, done)=>{
    users[profile.id] = profile;
    done(null, profile);
});
passport.serializeUser((user, done)=>{
    done(null, user.id);
});
passport.deserializeUser((id, done)=>{
    done(null, users[id]);
});
exports.users = users;
