Identical issues getting split in the list

Hello everyone. I’m having a problem where Sentry is not grouping identical bugs due to the “Issue #” field changing. If you take a look at the two screenshots below, you will see that the “Issue #” changed from “FESTALAB-D8” to “FESTALAB-E8”.

Split: https://www.dropbox.com/s/1ydc33v17lwae2y/split.png?dl=0

I don’t want that to happen. Is there a way to force “Issue #” to always be “FESTALAB” or to ensure that Sentry doesn’t split identical bugs like this?

Sentry is very liberal with its issue splitting. If there’s a slight variation in the stack trace, it will be considered a different issue, it doesn’t necessarily look at the message itself. One way to group things manually when you find an issue is being triggered by multiple code paths is to set a fingerprint: https://docs.sentry.io/learn/rollups/#custom-grouping
