This seems to be misrepresented in the documentation.

The documentation says it is metadata , but it is actually metadatas .

Hi, are you using the latest version? We have renamed metadatas to metadata a few versions ago, see #5871. It works in our website.

module.exports = {
  themeConfig: {
    metadata: [{name: 'foo', content: 'bar'}],
  },
};
