Invalid Step

​
Erroneous Code Example

This error occurs when you try to use a step that is not valid in the current context. In this example, the OutE<Knows> step results in edges, but the Out step can only be used on nodes. 
Query getUser() =>
    user <- N<User>::OutE<Knows>::Out<Knows>
    RETURN user

​
Solution

Use valid step types in your traversals. 
Query getUser() =>
    user <- N<User>::Out<Knows>::Out<Knows>
    RETURN user
