Invalid Field Access

Erroneous Code Example

This error occurs when you try to access a field that doesn’t exist on the inner type of an iterable variable.

Query addUser(userData: [{name: String, age: I64}]) =>
    FOR { name, age, nonexistent_field } IN userData {
        AddN<User>({name: name, age: age})
    }
    RETURN "Users added"

Solution

Ensure to only access fields that exist on the inner type.

Query addUser(userData: [{name: String, age: I64}]) =>
    FOR { name, age } IN userData {
        AddN<User>({name: name, age: age})
    }
    RETURN "Users added"
