使用Graph API分配应用保护策略时遇“No method match route template”错误

我需要通过PowerShell脚本创建并分配应用保护策略，目前除分配步骤外所有操作均正常。使用Graph Explorer测试分配策略的语法时，所有尝试均返回**"No method match route template"**错误。权限、策略ID及组ID均已验证无误，寻求解决帮助。

已分配策略的响应示例 #

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#deviceAppManagement/androidManagedAppProtections('{ID}')/assignments",
    "value": [
        {
            "id": "cb16bf46-1479-45b2-8221-2f4c5cada212_incl",
            "target": {
                "@odata.type": "#microsoft.graph.groupAssignmentTarget",
                "groupId": "{ID}"
            }
        }
    ]
}

当前测试情况 #

GET请求（正常返回无分配记录） #

GET https://graph.microsoft.com/v1.0/deviceAppManagement/androidManagedAppProtections/{ID}/assignments/
