TypeError: Cannot read property 'name' of undefined at t.render (botchat.js:20)

I can verify that the messages are going to the bot, but when the bot tries to return something. it fails, is there a specific version of bot chat I should use?

<script src="https://hbs.azureedge.net/public-websites/webchat/botchat.js"></script>

const params = BotChat.queryParams(location.search);
BotChat.App({
directLine: {
secret: '',
token: '',
domain: params['domain'],
webSocket: false // defaults to true
}
// sendTyping: true, // defaults to false. set to true to send 'typing' activities to bot (and other users) when user is typing
}, botContainer);

Error in console:
