`slug` is `undefined` when I track mark and children from internalLink

I’m getting this from my console when I track
internalLink - mark 
_key: "7e6ceaaccca5"
_type: "internalLink"
reference: {…}
    _ref: "6230af03-9c14-4316-aa6f-ba7903d72c51"
    _type: "reference"

internalLink - children 
_key: "7e6ceaaccca5"
_type: "internalLink"
reference: {…}
    _ref: "6230af03-9c14-4316-aa6f-ba7903d72c51"
    _type: "reference"

... arrrgh!What ... am I doing wrong?!

mmm... maybe I have to use
_rawText(resolveReferences: {maxDepth: 10})
in my page graphql query instead of just
to get the slug

OK I think I begin to understand how this works!So I used the
as written above and I did it like this :
  marks: {
    strong: (props) => <strong>{props.children}</strong>,
    em: (props) => <em>{props.children}</em>,
    internalLink: ({ mark: { reference }, children }) => {
      const { slug = {} } = reference;
      const href = `/${slug.current}`;
      return <Link to={href}>{children}</Link>;
and it works like a charm :)

Way to go David! I really like how you solved this thread by yourself 😄

Thanks David! After trying to work through this guide: https://www.sanity.io/guides/portable-text-internal-and-external-links I got stuck in the same spot.

This made the difference:
Guide Shows:

internalLink: ({mark, children}) => {
Changed it to:

internalLink: ({ mark: { reference }, children })

You saved the day!!!!
