As v2.2.0 has been released with support for @docusaurus/faster, I tried to enable it for our repository, but it fails with the following error if swcJsLoader: true, is enabled:

TypeError: Cannot read properties of undefined (reading 'tokenizePlaceholders')

It's not clear to me if the issue is at redocusaurus'es side or on the side of docusaurus.

The Spec can be found here. The full stack trace looks like this:

It's not clear to me if the issue is at redocusaurus'es side or on the side of docusaurus.

Might be worth reporting it there too (you can link this issue), since it's still experimental and your normal build works (I guess?)

Hi @thde @rohit-gohri ,
same issue on some of our api docs. Has something to do with markdown codeblocks in the description field of a parameter.

But after i followed the first line after the "please report to marked...", i landed somewhere in the prism.languages.php definitions.

So, I got it working with adding the additional language php into the docusaurus.config.js as described here : https://docusaurus.io/docs/markdown-features/code-blocks#supported-languages

prism: {
   additionalLanguages: ['php']
}

Also not happening, if you do a docusaurus build --dev.

But - not sure if that makes things easier to permantly fix.

That's it! If you follow the generated code in the stack trace you end up in ***/build/__server/assets/js/f0ad3fbb.8489e1b5.js:50825:40:

Prism.hooks.add('after-tokenize', function (env) {
   Prism.languages['markup-templating'].tokenizePlaceholders(env, 'php');
});

After adding php to additionalLanguages , the build worked for me too.
