通过API创建Facebook广告时enroll_status参数报错求助

已添加standard_enhancements > enroll_status > OPT_OUT参数，但创建广告时仍提示未提供该参数，问题与Facebook开发者社区相关帖子情况类似。

排查建议 #

• 检查参数层级：确认standard_enhancements严格嵌套在degrees_of_freedom_spec > creative_features_spec下，层级错位会导致API无法识别参数。
• 验证参数值大小写：确保enroll_status的值为大写的OPT_OUT或OPT_IN，API对大小写敏感，非大写值会被判定为无效。
• 多创意场景检查：如果请求包含多个创意对象，每个创意都需要单独配置standard_enhancements，不能仅在全局配置。
• 确认API版本：切换到文档推荐的稳定版本（如v18.0及以上），旧版本可能存在参数识别兼容问题。
• 变量替换验证：检查请求中{result=videoThumbnailRequest...}这类占位符是否已替换为实际有效值，未替换的占位符可能导致API解析请求出错，间接引发参数未识别报错。
