RobotFramework从CSV取变量报错：${description}参数异常

原本使用PyCharm开发的RobotFramework测试用例，迁移到VSCode后，调用Create And Approve A New Request关键字时，${description}变量触发Unexpected argument错误。尝试清空测试用例、修改CSV文件路径后，问题仍未解决。

排查与解决方向 #

• 检查VSCode插件兼容性：确保安装的是Robot Framework Language Server插件，且版本与当前RobotFramework、DataDriver库版本匹配。旧版本插件可能存在参数解析逻辑bug。
• 核对参数一致性：确认关键字定义的5个参数顺序、数量，与测试用例调用、CSV表头列的顺序完全一致，无多传、漏传情况。
• 验证CSV格式：确认CSV每行的列数与表头一致（共6列），分隔符为分号;，${description}列无换行、特殊引号等可能导致解析失败的字符，可临时替换为纯文本测试。
• 清理VSCode缓存：关闭VSCode后删除项目下.vscode/目录的缓存文件，重新打开项目，避免旧缓存干扰参数解析。
• 检查变量作用域：确认${description}变量在DataDriver加载后可正常被测试用例读取，可通过添加Log ${description}语句验证变量是否正确赋值。
