Custom Markdoc's components work on local with wrangler but fail online with Pages

I've create a custom Markdoc components following this guide: https://markdoc.dev/docs/examples/react In local, the component (Counter) works ok, and when consologing you get this:

{
      '$$mdtype': 'Tag',
      name: 'Counter',
      attributes: [Object],
      children: []
    }

{
      '$$mdtype': 'Tag',
      name: 'Counter',
      attributes: [Object],
      children: []
    }

But on deploying to Pages I get an error

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined.

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined.

and the console:

{
      '$$mdtype': 'Tag',
      name: '_R',
      attributes: [Object],
      children: []
    }

{
      '$$mdtype': 'Tag',
      name: '_R',
      attributes: [Object],
      children: []
    }

So it's like the render is working locally and not online. I've spotted the 'rendering error' in the transform method:

const ast = parse(markdown) 
const config = {
        tags: { counter, },
       
    }
    return transform(ast, config)

const ast = parse(markdown) 
const config = {
        tags: { counter, },
       
    }
    return transform(ast, config)

` What else can I do to debug it? Is the bug in Worker backend?? (because Markdoc works ok locally)

@sergiodxa I've followed your guide to implement Markdoc components, and it works locally, but I get this error when deploying on CF Pages. Have you make it work on CF? thx https://sergiodxa.com/articles/parse-markdown-with-markdoc-in-remix
