How to support code blocks without syntax highlighting?

If I just add:

```ts
codeBlockPlugin({
    defaultCodeBlockLanguage: 'js',
})
```

I get:

> No CodeBlockEditor registered for language=null meta=null

If I don't add plugin at all, I get:

> Error: no MdastImportVisitor found for code {"type":"code","lang":null,"meta":null,"value":"Before initiating

I just want simple code block without highlighting.
