# E205

# 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.

<CodeGroup>
  ```rust queries.hx theme={null}
  QUERY addUser(someField: U32) =>
      user <- AddN<User>({someField: someField})
      RETURN user
  ```

  ```rust schema.hx theme={null}
  N::User {
      someField: String,
  }
  ```
</CodeGroup>

## Solution

  <Tab title="Solution 1">
    Either change the type of the field in the schema to `U32`.

    <CodeGroup>
      ```rust queries.hx theme={null}
          QUERY addUser(someField: U32) =>
              user <- AddN<User>({someField: someField})
              RETURN user
      ```

      ```rust schema.hx theme={null}
      N::User {
          someField: U32,
      }
      ```
    </CodeGroup>
  </Tab>

  <Tab title="Solution 2">
    Or change the value you're providing to a string.

    <CodeGroup>
      ```rust queries.hx theme={null}
          QUERY addUser(someField: String) =>
              user <- AddN<User>({someField: someField})
              RETURN user
      ```

      ```rust schema.hx theme={null}
      N::User {
          someField: String,
      }
      ```
