Sentry-browser: beforeSend not filtering out all

Hey. We’re trying to filter out a really noisy error in a 3rd party vendor script - unable to execute code from a freed script. Yay IE.

However, our attempts to silence it from sentry have been somewhat fruitless. We’ve tried a few options: ignoredErrors, beforeSend, old and new and everything else.

Finally, beforeSend has reduced volume, but we’re still seeing them. I’d like to think that our code should be good enough:

where are we going wrong? :slight_smile:
thanks.
