Extending strapi plugin

When I replace the file contents with just an empty module.exports it gives me the following error:

TypeError: Cannot read properties of undefined (reading                 ││   'contentTypes')

This is what i mean by “empty module.exports”:

module.exports = (plugin) => {
    console.log('plugin', plugin);
};

The plugin does print, and the error proceeds.

I tried this because it more closely matches what’re on the official docs.
