Sourcemap NestJS

[pasalino]

I'm using NestJS in production for a web-based project.

Since a couple of week (I think so, because i realised only in a couple of days) that my sentry give to me an alert.

This alert appear because the sourcemap is not present in a release.
I use in production this library that help me to show the stacktrace in TS in my console https://www.npmjs.com/package/source-map-support .
As Sentry suggest in it's troubleshooting https://docs.sentry.io/platforms/javascript/sourcemaps/troubleshooting_js/#verify-you-are-not-using-the-source-map-support-package
it is not necessary upload a sourcemap and then, until now we see the stacktrace without this kind of alert.

Why now we started to see this alert despite we see the correct stacktrace provided from source-map-support ?
