Incorrect source map reporting in Sentry

We have been seeing this a bunch and yesterday was kind of the straw that broke the camel’s back for me in terms of just ignoring this. We update our source maps during our deployments by uploading them to Sentry as part of the deployment process and tag everything. We had a build go out yesterday that removed a certain library, nouislider, as we built a new React slider component so we no longer had a use for it. We replaced all instances of the slider in our code base with the new React version and then this morning we saw the following issue pop up in Sentry: https://www.dropbox.com/s/e7isp12g9xh9lpe/Screenshot 2016-08-09 09.57.10.png?dl=0

As you can see, not only is the error reporting that it came from nouislider but its reporting the method as getValuesFromString which is actually part of our time utils module. I believe the error is actually valid as I’ve seen it before in our code base but what its mapping back to is completely not as that code doesn’t even exist anymore in our codebase.

Any idea what is going on here?

OK, lol, so let me just make sure i’m getting this right:

1. Upload app.min.js and app.min.js.map to sentry
2. Upload app.min.js and app.min.js.map to our production server

Is that correct?

Thank you, I meant to close it yesterday but forgot, my apologies.
