I’m getting this same error, but for exception while calling captureException.

TypeError: Cannot read properties of undefined (reading 'exception')

How is the error handling within the sentry node package so extremely poor, that errors like this bubble up with vague messaging instead of being caught within the lib, with proper custom errors (with codes) thrown? This is basic package authoring stuff folks.

There is some funky stuff going on in the kafkajs package: https://github.com/tulios/kafkajs/blob/master/src/producer/partitioners/legacy/randomBytes.js

I can’t pinpoint the exact problem yet but I bet it has to do with this.
