"Call to undefined method Illuminate\\Events\\Dispatcher::fire()"

I got this error, i don't know why, i use pusher via database and broadcast and it's works fine, but with this package it gives me this error

"Call to undefined method Illuminate\\Events\\Dispatcher::fire()"

This is because:

1. There was an error talking to Pusher. Likely invalid credentials. Try checking those and clearing cache.
2. The code has a bug w/ Laravel 5.8+ since it uses a method that's been deprecated, so the real error is buried under this exception.
