連報三錯

[Vue warn]: Invalid prop: custom validator check failed for prop "fileList".

[Vue warn]: Invalid prop: custom validator check failed for prop "items".

[Vue warn]: <transition-group> children must be keyed: <div>

 

后面兩條真是無跡可尋，ctrl+F都沒找出items和<transition-group>

 

 

 最后解決了第一條后面兩條也沒了：

<a-upload name="file" :before-upload="beforeUpload" list-type="picture" :multiple="false" :fileList="downloadFiles" :remove="handleDownloadFileRemove"
                :customRequest="downloadFilesCustomRequest">

 

 

 

a-upload綁定的fileList里有一個uid錯誤的取到了undefined導致的，取到正常的uid后就不報錯了。
