Call to undefined method Monolog\Handler\PsrHandler::pushProcessor()

Using Bugsnag, I got the following error in my trace:

array:1 [▼
  "exception" => Error {#2004 ▼
    #message: "Call to undefined method Monolog\Handler\PsrHandler::pushProcessor()"
    #code: 0
    #file: "

/yorcreative/laravel-scrubber/
src/Handlers/ScrubberTap.php"
    #line: 13
    trace: {▶}
  }
]

This is the handler object:
