在SharePoint列表上使用自定义JavaScript的Nintex表单无法获得所需的用户

Question

带有自定义JS的Nintex NewItem Form，可以获取特定于用户选择的表单数据（位置）的ppl，对某些选择非常有用，而对其他选择则不起作用。

我已验证关联的SP列表数据正确-3个列表：

• 位置
• 部门
• 批准人详细信息

“审批者详细信息”列表具有“位置”和“部门”的查找列。 Nintex表单按位置过滤部门。

我认为基于F12控制台结果，对于问题位置值，返回的值为null，但我不知道为什么。

以下是JSFiddle

我希望JavaScript根据位置信息从批准者详细信息中获取“编码器1”或“编码器2”，并在表单上填充人员字段，该字段对于大多数位置都适用，但是...

  

问题：对于许多位置，都不会在表单字段上检索和填充用户。
