        .withWhere({
            operator: "Equal",
            path: ["_additional", "id"],

Hi Mike, you can get the object ID as shown here:

That look right to me, but I think the ID filter perhaps looks incorrect. I think (source) the filter should look like this:

  .withWhere({
    operator: 'Equal',
    path: ['id'],
    valueText: postId,
  })

I also notice you’re using valueString - pls note that string datatype has been deprecated and they will be changed to text when you upgrade Weaviate.

Hi @Crazy_Mike - I’ve also moved this to our Support topic. :slight_smile:
