Recently I discovered that you can upload javscript sourcemaps to sentry during your release process. This gives much better information when viewing issues on sentry.

For my nextjs projects my release scripts look something like this ..

sentry release new "$RELEASE" --org myorg --project myproject
sentry release set-commits "$RELEASE" --auto --org myorg --project myproject
sentry sourcemaps upload .next/static --org myorg --project myproject --release "$RELEASE" --url-prefix "~/_next/static"

sentry release finalize "$RELEASE" --org myorg --project myproject
