我的工作在消息一开始就失败了：
"@*" and "@N" are reserved sharding specs. Filepattern must not contain any of them.
我已将目标位置更改为默认值（电子邮件地址）以外的其他内容，其中包含@符号，但我仍然可以看到它正在使用我无法编辑的路径中的临时目标。
以前有没有人遇到过这个问题？我有一个只有65k行的文件，我可以预览Data Prep中的所有完整数据，但是当我运行它失败时，这是非常繁琐的，并且如果不能运行那么〜3小时清理排水管。 （我很欣赏它不是为此设计的，但Excel是一个母马，所以它似乎是一个很好的解决方案！）
