@franciscofsales how do you think, is it a lot of work? Are you going to implement it any time soon?

Thanks in advance!

Having @sentry/node v7 installed next to winston-sentry-log and it's v6 dep tree...still seems to cause all errors to look like this:
"Cannot read properties of undefined (reading 'exception')"
