This is probably related to:

• When using @docusaurus/faster, if there is some Chinese in the md file when packaging on version 3.6, an error message will be displayed, such as byte index 4 is not a char boundary. facebook/docusaurus#10646

Building with COLORBT_SHOW_HIDDEN=1 SKIP_HTML_MINIFICATION=true RUST_BACKTRACE=1 RUST_BACKTRACE=full NODE_ENV=production yarn build don't seem to help

@taraspos answering your comment here: facebook/docusaurus#10556 (comment)

If it works with rspackBundler: false but doesn't with rspackBundler: true, then it's very likely a Rspack bug that you should report to the Rspack team directly (or maybe SWC, not sure).

It can be reproduced using latest Docusaurus canary using @rspack/[email protected] that recently upgraded to SWC core to v10: https://rspack.dev/blog/announcing-1-2#upgrade-swc-plugins

When disabling Docusaurus Faster options related to SWC, it still reproduces:

const config: Config = {
  future: {
    v4: true,
    experimental_faster: {
      swcJsLoader: false,
      swcJsMinimizer: false,
      swcHtmlMinimizer: false,
      lightningCssMinimizer: true,
      rspackBundler: true,
      mdxCrossCompilerCache: true,
      ssgWorkerThreads: true,
    },
  },
}

However, when disabling Rspack (using Webpack), it doesn't crash anymore.
(in this case it's not using the built-in Rspack SWC support so it's not 100% the same SWC)

const config: Config = {
  future: {
    v4: true,
    experimental_faster: {
      swcJsLoader: true,
      swcJsMinimizer: true,
      swcHtmlMinimizer: true,
      lightningCssMinimizer: true,
      rspackBundler: false,
      mdxCrossCompilerCache: true,
      ssgWorkerThreads: true,
    },
  },
}

However, we still get various errors:

 

[ERROR] Client bundle compiled with errors therefore further build is impossible.

Your repro is not really usable as is since the data folder doesn't contain the Sanity files, requiring env variables to be set.

However, fixing the errors above does not fix the Rspack/SWC crash.

Reverting to Rspack 1.1 fixes the bundling crash:

  "resolutions": {
    "@rspack/core": "1.1.8"
  },

@slorber, thanks for such a detailed response!

[slorber]

The bug has been fixed in our deps, I guess it should work soon on our next release

• [Bug]: width 3 given for non-narrow character error when building certain libraries web-infra-dev/rspack#9075
• [Bug]Panic in non-narrow character when generate source map swc-project/swc#10010

[taraspos]

Thanks @slorber !

np 👍

Try Rspack 1.2.3, this might fix the problem (not sure):
