## Use Form's `setFieldsValue` method to report an error if the object type contains `null`
When we try to set the form value using the `setFieldsValue` method in the form instance of the form component, if the passed object contains the type null, such as:
```tsx
// This is not real world code, just for explain
import { Form } from 'antd';
type Test = {
value: string[] | null;
};
export default () => {
const [form] = Form.useForm<Test>();
form.setFieldsValue({
value: null, // Error: Type "null" cannot be assigned to type "string[] | undefined".
});
};
```
If you encounter the above error, please check the current project `tsconfig.json` contains the following configuration:
```json
{
"strictNullChecks": true
}
```
The above problem occurs if `strictNullChecks` is set to `true`, If you can determine the project don't need this configuration (see [strictNullChecks](https://www.typescriptlang.org/zh/tsconfig#strictNullChecks) to judge whether need the configuration). You can try changing to `false` to turn off the control strict check. However, if you do need to enable this feature, you can avoid this situation by using other types instead of `null` when designing types
