# FieldValue

The ancestor for custom field value entities.

## Properties

| Name | Type | Description |
| --- | --- | --- |
| type | `string` literal |    The discriminator that identifies the kind of field value.     For custom fields, set this property to the corresponding custom field type, such as `'string'` or `'enum'`. For predefined fields, such as `comments` and `attachments`, YouTrack infers the discriminator from the field name, so you can omit this property.    |
