+`duplicate_policy` 只接受 `fail` 和 `use-existing`。省略该字段或发送 `null`
+时使用 `fail`。工作流 ID 尚未使用时，两种策略都会创建一次运行。
+
+| 策略 | 已存在活动运行 | 现有运行已关闭 |
+| --- | --- | --- |
+| `fail`（默认） | 拒绝重复启动。 | 拒绝重复启动。 |
+| `use-existing` | 返回现有的 pending、running 或 waiting 状态运行，不再启动新运行。 | 拒绝重复启动。 |
+
+两种策略都不会重新打开已关闭的运行。新的执行应使用新的工作流 ID。
+`reject` 不是有效值，会返回 HTTP 422。
