I get this error pretty consistently under the following conditions:

Have kui ui open in a browser window
perform graceful shutdown

I’m not certain if it is expected for Queue.client to be null. If it is, then Queue.prototype.card should first check if this.client exists before calling this.client.card. Same with Queue.prototype.cardByType
