yarn start doesn't reflect updates on .mdx on local

[Rindrics]

Context

Adding new page under docs/

Problem

• Updates on new- and preexistent- .mdx files aren't reflected to the page served by yarn start
  • yarn says ✓ Compiled in 2.8s (NNNN modules) every time I update .mdx
• Clicking link to the new page, such as link on side navigation column and DocCard results in 404

Spec of the environment the problem observed

• OS: macOS 15.1
• Processor: 2.3 GHz Quad-Core Intel Core i7
• RAM: 32 GB 3733 MHz LPDDR4X
• Node.js: v22.3.0

Additional Information

Although the causal relationship is unclear, yarn build fails with the following error:

❯ yarn build
yarn run v1.22.19
