Exception: Cannot set property 'services_only_admins' of undefined

My bot based on the slack-client node module crashed a couple of times today. Looks like it got a message it couldn't handle. This is the mysterious backtrace.

/app/node_modules/slack-client/src/client.js:546
        return this.team.prefs[message.name] = message.value;
