The "path" argument must be of type string or an instance of Buffer or URL. Received undefined

Hello, I'm having some issues during build process using:

"next": "14.0.0",
"nextra": "2.13.2",
"nextra-theme-docs": "2.13.2",

When i start building i get this error:

Failed to compile.

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined
    at readdir (node:fs:1418:10)

next.config.js:

const withNextra = require('nextra')({
  theme: 'nextra-theme-docs',
  themeConfig: './theme.config.jsx'
})

module.exports = withNextra(nextConfig)

theme.config.jsx on the root level of the project aka the same as next.config.js

export default {
  logo: <span>My Nextra Documentation</span>,
  project: {
    link: 'https://github.com/shuding/nextra',
  },
  // ... other theme options
};

Any idea what might cause the issue?

Nextra doesn't yet support the App router, but you can make a Pages directory side by side.
