Qlik Playground - not valid ApiKey

[shestac92]

Hello,

I tried to launch the AirBnB  playground sample, but I got authenticated error because the config object suggested by Playground is the following:

 let config = {
	url: 'wss://playground-sense.qlik.com:443/playground/app/2b10add1-472f-4192-aac9-44a99125825c',
	apiKey: 'undefined',
	appname: '2b10add1-472f-4192-aac9-44a99125825c'
}

As you can see, the apiKey is undefined. 

My question is - how can I get a valid apiKey to try the PG samples? I have checked some quick start guides on launching PG samples, I did exactly the same steps, but every time I got undefined apiKey and it doesn't allow me to connect to the PG.

Thanks!
