Note this frame:

handleProfileResult@https://www.crunchbase.com/main.4a4119c3cdfd10266d84.js:146:1018410

In Sentry it's displayed as

function: "handlePro"
abs_path: "fileResult@https://www.crunchbase.com/main.4a4119c3cdfd10266d84.js"

It's the only frame in the whole stack trace that is messed up.

On the first glance it looks like some regex matches the file substring there as a special delimiter :)

[github-actions]

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!

I mean, it's still a legit issue, and keeps popping up from time to time in our project ("profile" is a part of our domain terminology, so we cannot simply rename all occurrences in the code to make Sentry SDK happy)

I confirm there are other inputs that produce unexpected results when run through

sentry-javascript/packages/browser/src/tracekit.ts

Touching that regexp is going to require the due diligence (and possibly regular expressions are not the best tool for the job).
