Internal links in a v2 project suddenly stopped working, but the issue was fixed by updating the query.

internalLink: (props: any) => {
      console.log('props : ', props);
      return (
        <ArticleLink type={ArticleLinkType.Internal} href={'#'}>
          {props.node.text}
        </ArticleLink>
      );
    },

props :  {
  node: {
    _key: '835e9c573f05',
    reference: {
      _ref: '18124180-6ce3-4b31-b12e-bf9ad911bf26',
      _type: 'reference'
    },
    _type: 'internalLink',
    text: 'interal'
  },

groq`*[_type == "article" && content.slug.current == $slug][0]{
          ...,
          content{
            ...,
            "media": ${groqFormatMedia('media')},
            body[] {
              ...,
              ...select(
                @._type == "fileLink" => @ {
                  ...,
                  file{
                    ...,
                    "url": asset->url,
                  },
                },
              ),
            }
          },
