  The Airbrake notifier makes it simple to ignore this chaff while still processing legitimate errors. Add filters to the notifier by providing filter functions to `addFilter`.
  -`addFilter` accepts the entire [error notice](https://airbrake.io/docs/#create-notice-v3) to be sent to Airbrake, and provides access to the `context`, `environment`, `params`, and `session` values submitted with the notice, as well as the single-element `errors` array with its `backtrace` element and associated backtrace lines.

  The return value of the filter function determines whether or not the error notice will be submitted.
  * If a null value is returned, the notice is ignored.
