### FAQ

### What happened?

I face an issue of Chrome Lighthouse Audit.

I build a web app that loads Sock JS minified file.

The file is -> [https://unpkg.com/sockjs-client@1.5.0/dist/sockjs.min.js][1]

As you can see, there is **//# sourceMappingURL** at the end of the file.

Also, there is the source map file -> [https://unpkg.com/sockjs-client@1.5.0/dist/sockjs.min.js.map][2]

[1]: https://unpkg.com/sockjs-client@1.5.0/dist/sockjs.min.js
[2]: https://unpkg.com/sockjs-client@1.5.0/dist/sockjs.min.js.map

### What did you expect?

I think that warning should not appear.

### What have you tried?

I have tried to load the SockJS minified file from the CDN and do the Lighthouse Audit several times, but it's still produce the same warning :

**Missing source maps for large first-party JavaScript**

Environment :

- Ubuntu 22.04
- Brave Browser v1.50.114

Am I missing something here or there is a bug in the Lighthouse?

Thank you.
