I see where the response object has been replaced with the messages object and this should be Livewire.hook('message.received', (message, component) => {}) rather than livewire.hook('responseReceived', (component, response) => {}).
HOWEVER, this is not an upgrade from V 1 to V 2 … it is a fresh app and a fresh install of Livewire.
The error is indicated in hookmanager.js line 30 which, of course, is not my coding.
This is the offending component: https://gist.github.com/b76132f087e50d9f83404eb63bc55cbf
and its blade: https://gist.github.com/bd17f5f4629e17915ddc2391a83f15ac
