OrientDB 3.0.4 Console EMBEDDEDLIST CREATE VERTEX

问题:

It appears that console application in OrientDB 3.0.4 is not backward compatible with OrientDB 3.0.2 for creating Vertex having EMBEDDEDLIST.

Following Query fails in OrientDB 3.0.4 console:

 CREATE VERTEX Profile SET name = "John", phone = [{ "@type":"d", "number" : "212" }] 

How can I resolve the issue? What are the changes for v3.0.4 and where can I find updated documentation?

The issue is that you've declared your property as "Phone" and then you're trying to create your vertex using the name "phone" in lowercase which doesn't match the schema. Also there's no need to use square brackets so instead of that last query, try using:

CREATE VERTEX Profile SET name = "John", Phone = { "@type":"d", "number" : "212"}
