Error occurs when building after adding "hi" or "th" to language prop

[andrew-polk]

After adding "hi" or "th" to the language prop (e.g. language: ["en", "hi"]), docusaurus build gives

TypeError: Cannot read properties of undefined (reading 'init')
[ERROR] Unable to build website for locale en.
[ERROR] Error: Failed to compile with errors.

[INFO] Docusaurus version: 2.4.3

error Command failed with exit code 1.

Seems to be caused by https://github.com/MihaiValentin/lunr-languages/issues/101.

Note that while I am using docusaurus v2, this error occurs with v3 as well. I used https://docusaurus.new/, just added the dependency, and added

  themes: [
    [
      require.resolve("@easyops-cn/docusaurus-search-local"),
      {
        language: ["en", "hi"]
      },
    ],
  ],

to the config.

That gave:

Seems to be a lunr / lunr-languages issue, please share the result of yarn why lunr and yarn why lunr-languages

[andrew-polk]

In my v2 project:

$ yarn why lunr
...
=> Found "lunr@2.3.9"
info Reasons this module exists
   - "@easyops-cn#docusaurus-search-local" depends on it
   - Hoisted from "@easyops-cn#docusaurus-search-local#lunr"

$ yarn why lunr-languages
...
=> Found "lunr-languages@1.9.0"
info Reasons this module exists
   - "@easyops-cn#docusaurus-search-local" depends on it
   - Hoisted from "@easyops-cn#docusaurus-search-local#lunr-languages"

In the CodeSandbox using v3:

yarn why lunr

info Reasons this module exists
   - "@easyops-cn#docusaurus-search-local" depends on it
   - Hoisted from "@easyops-cn#docusaurus-search-local#lunr"

yarn why lunr-languages
