### Description Sometimes while testing this I get: ``` BadRequestError: checks.state argument is missing at <folder>/node_modules/express-openid-connect/middleware/auth.js:105:31 at processTicksAndRejections (internal/process/task_queues.js:97:5) ``` This happens randomly after logging in. ### Reproduction It happens especially often at the first login, but sometimes just randomly after logging in. My code: ```js require('dotenv').config() const express = require('express') const app = express() const { auth } = require('express-openid-connect') const config = { authRequired: false, auth0Logout: true, issuerBaseURL: process.env.ISSUER_BASE_URL, baseURL: process.env.BASE_URL, clientID: process.env.CLIENT_ID, secret: process.env.SECRET, } app.use(auth(config)) app.get('/', (req, res) => { res.send(req.oidc.isAuthenticated() ? 'Logged in. Welcome!' : 'Logged out. <a href="/login">Login?</a>') }) app.listen(3000) ``` ### Environment - **Version of this library used:** 2.0.0 - **Version of the platform or framework used, if applicable:** Express version 4.17.1 - **Other relevant versions (language, server software, OS, browser):** Node.js version 12.18.4 installed with nvm, macOS 10.15.6, Chrome 85.0.4183.121 - **Other modules/plugins/libraries that might be involved:** dotenv version 8.2.0

I hope this helps!

Best,
Alex
