Type Mismatch

Erroneous Code Example

This error occurs when the type of a value you’re providing doesn’t match the expected field type defined in your schema. For example, the field age is defined as an integer in the schema but you’re providing a string.

QUERY addUser(someField: U32) =>
    user <- AddN<User>({someField: someField})
    RETURN user

N::User {
    someField: String,
}

Solution

Solution 1
Solution 2

Either change the type of the field in the schema to U32.

    QUERY addUser(someField: U32) =>
        user <- AddN<User>({someField: someField})
        RETURN user

N::User {
    someField: U32,
}

Or change the value you’re providing to a string.

    QUERY addUser(someField: String) =>
        user <- AddN<User>({someField: someField})
        RETURN user

N::User {
    someField: String,
}
