Load data into Neo4j [Neo4J Output]

[po...@gmx.com]

Hello Dear Hop Creators!



I'm trying to load data into Neo4j db. All works great except vector search
properties; embeddings.



In Neo4j syntax we use:

CREATE (Product1:Product {id: 10, name:'Some name', description:'Some product
desc', embedding: [-1.00518711e-01, ...,-2.13430752e-03]})



'Embedding' property is created as Array.

Problem is that with 'Neo4J Output' hop I cannot define this type of data
('Property type' in 'To node' tab).

If I send it as text it will be not searchable.



Any idea how to create nodes with right properties?





Best!

If writing the property as String doesn't work, I guess we'll have to work
something out.
Please create a feature request ticket [1] and we'll look into it.
