Hmm, that's bad! But we'll take a look at it! Thank you for reporting

Can you just share more information @Niofh? As such which version, OS, etc. Or even maybe, a repo or a codesandbox link, with the same configuration settings you're using, just to make it reproducible from our side.

This was a showstopper bug for me, but I managed to make Docz work nevertheless by using the gatsby theme.

There are conflicting dependencies, so installation should be as follow:

npm install --save-dev gatsby@^4.x docz@latest gatsby-theme-docz@latest @emotion/core@^10.x

Seems like the latest version of @emotion/core is causing some issues.

After that, remember to run npx gatsby develop (instead ofdocz dev), and so forth for the rest of commands

There will be some warnings in the console, ignore them:

warn Plugin gatsby-source-filesystem is not compatible with your gatsby version 4.5.4 - It requires
gatsby@^2.2.0
warn Plugin gatsby-plugin-catch-links is not compatible with your gatsby version 4.5.4 - It requires
gatsby@^2.0.0
warn Plugin gatsby-plugin-emotion is not compatible with your gatsby version 4.5.4 - It requires
gatsby@^2.0.0
warn Plugin gatsby-source-filesystem is not compatible with your gatsby version 4.5.4 - It requires
gatsby@^2.2.0
warn Plugin gatsby-plugin-catch-links is not compatible with your gatsby version 4.5.4 - It requires
gatsby@^2.0.0
warn Plugin gatsby-plugin-emotion is not compatible with your gatsby version 4.5.4 - It requires
gatsby@^2.0.0

Also, I experienced that inlining Docz config in gatsby-config.js seems to be breaking something, so instead of this:

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-theme-docz',
      options: {
        /* your custom options */
      },
    },
  ],
}

do this:

// gatsby-config.js
module.exports = {
  plugins: ['gatsby-theme-docz']
};
// doczrc.js
module.exports = {
  /* your custom options */
}
