I want to know what Unreferenced means in an event’s Images Loaded / Source Maps section, whether that debug file or source map status is a problem, and how it relates to readable stack traces and symbolication.

Unreferenced means Sentry found that image (debug file or source map candidate) on the event, but none of the stack frames needed it, so Sentry didn’t use it for symbolication.

If the stack trace is already readable, you can safely ignore Unreferenced rows. Extra loaded modules or uploaded artifacts that the stack trace didn’t use commonly show this status.

If the stack trace is still minified or missing symbols, Unreferenced isn’t the issue to focus on. Instead, check the frames or images marked Missing, Error, or something similar, then follow Troubleshooting Source Maps for JavaScript or Debug Information Files for native.

To see how a frame was resolved, see How were my source maps resolved?.
