Is it possible to graphql query a block within lexical?

I am getting an infamous cast error when a block provides relationships to, in this case, a page with at least one media field:

CastError: Cast to ObjectId failed for value "info" (type string) at path "_id" for model "media"

And my query ist:

{
  Pages {
    docs {
      aLexicalField
    }
  }
}

Must be a db gltich due to many migrations, closing
