​
Non-Iterable Variable

​
Erroneous Code Example

This error occurs when you try to use a non-iterable variable in an iteration context. In this example, the parameter name is not a collection, so it cannot be used in an iteration context. 
Query addUser(name: String) =>
    FOR n IN name {
        AddN<User>({name: n})
    }
    RETURN "User added"

​
Solution

Ensure variables used in iterations are collections or arrays. 
Query addUser(names: [String]) =>
    FOR n IN names {
        AddN<User>({name: n})
    }
    RETURN "Users added"
