Problem description

The following snippet returns an error, but should not according to the documentation

        client.indices().create(b -> b
                .index("wikipedia-german")
                .mappings(mb -> mb
                        .properties("paragraphs", pb -> pb.nested(nb -> nb
                                .properties("vector", vb -> vb.denseVector(t -> t))
                                .properties("text", tb -> tb.text(t -> t.index(false))))
                        )
                )
        );

results in

Exception in thread "main" co.elastic.clients.util.MissingRequiredPropertyException: Missing required property 'DenseVectorProperty.dims'

However, the documentation for 8.11 states at https://www.elastic.co/guide/en/elasticsearch/reference/current/dense-vector.html#dense-vector-params:

 dims
    (Optional, integer) Number of vector dimensions. Can’t exceed 4096. If dims is not specified, it will be set to the length of the first vector added to the field.

Hello! This was recently fixed with #756, updating the client to a more recent version should solve this.
