DROP Can Only Be Applied to Traversals

Erroneous Code Example

This error occurs when you try to use DROP on an expression that is not a traversal.

QUERY deleteValue(value: String) =>
    DROP value

Solution

Ensure DROP is applied to a traversal that returns nodes, edges, or vectors.

QUERY deleteUser(id: ID) =>
    user <- N<User>(id)
    DROP user
N::User {
    name: String,
}
