Don't sample (or capture) 4xx errors sentry-fastify

[karmic ice]

^ title-> is there a way to avoid capturing (or significant reduce sampling) on 4xx errors using the fastify-sentry error handler? It doesn't seem like setupFastifyErrorHandler takes any options

[quick ruin]

you can filter errors by configuring a beforeSend function. You can find the docs here: https://docs.sentry.io/platforms/javascript/configuration/filtering/

And we are currently working on filtering 4xx spans in node: https://github.com/getsentry/sentry-javascript/issues/11720
