Acumatica自定义端点设置Attributes失效：PUT请求无法赋值

• 自定义端点为从零创建（非默认端点扩展），已在Project Task节点下添加Attributes明细节点，字段配置与默认端点完全一致
• GET请求可正常获取属性值，但PUT请求返回错误，提示必填属性Category为空
• 涉及的CATEGORY为文本类型属性，并非下拉框类型

PUT请求内容 #

{"TaskID": {"value": "WEBDEVte"},"ProjectID": {"value": "PR00000138"},"Description": {"value": "Web Development"},"Status": {"value": "Active"},"Attributes": [{"AttributeID": {"value": "CATEGORY"},"Value": {"value": "Gen"}}],"rowNumber": 0,"delete": false}

该PUT请求在默认端点可正常执行，仅自定义端点失效，怀疑是端点UI字段配置问题，寻求解决帮助。
