Hello @canopus1io. Please provide a reproduction repository or online demo. For background, see Why reproductions are required. Thanks ❤️

Maybe related to web-infra-dev/rspack#7647

Can you provide more information for debugging?

[SyMind]

@canopus1io Can you check the correctness of the generated source map? Check where the source map is problematic.

[gitim]

I have the same issue after web-infra-dev/rspack#7647. Source map genereated by rspack@1.0.0 is about ~28MB, by rspack@1.0.1 the source map is incomplete and only ~5MB.

@gitim Please provide the a demo to reproduce the issue.

Hey hi, guys 👋

Would like to refer for this comment:
web-infra-dev/rspack#7914 (comment)

It seems that the issue is in optimization configurations.

Because when I'm disabling it or replacing SwcJsMinimizerRspackPlugin with TerserPlugin - the source-maps are generated properly.

Potentially related: our project's sourcemaps are all incomplete. E.g. in every chunk, every files has only a few lines covered with sourcemaps, the rest of the lines having empty mappings.

Minification doesn't matter, but replacing SWC with Babel gives sourcemaps.

Unfortunately couldn't yet reproduce in a small project.

Should be fixed in the next release, see: web-infra-dev/rspack#7991
