Errors being incorrectly lumped together

[short mantle]

I've seen this happen many times and I figured it was a Sentry issue that would eventually get resolved, but that doesn't seem to be happening.

My problem is this: Sometimes some errors are being lumped together as if they're the same when they're not at all the same. Today, an issue that was resolved got regressed but when I looked into it, it wasn't the same error at all - but that's only visible when I look into "more events" and see that it's completely different.

Why does this happen and how can i avoid it?

From the AI in the docs:

I guess you could also use spans: https://docs.sentry.io/platforms/javascript/guides/node/tracing/span-metrics/

sentry calculates a "fingerprint" based on the error type and stack trace, which you can see at the bottom of the page.
