Tailwindcss v4.0.0 not working on fumadocs-ui

[shiqocred]

To Reproduce

1. i clone project from examples/openapi
2. bun dev
3. error

Error: Package path ./css/black.css is not exported from package /Users/macpro/Downloads/fumadocs-dev/examples/openapi/node_modules/fumadocs-ui (see exports field in /Users/macpro/Downloads/fumadocs-dev/examples/openapi/node_modules/fumadocs-ui/package.json)

Current vs. Expected behavior

I have done the steps to use tailwindcss v4 like what in examples but an error appears

Error: Package path ./css/black.css is not exported from package /Users/macpro/Downloads/fumadocs-dev/examples/openapi/node_modules/fumadocs-ui (see exports field in /Users/macpro/Downloads/fumadocs-dev/examples/openapi/node_modules/fumadocs-ui/package.json)

i think this error comes from fumadocs-ui
