Hello @hong_yip,
The operating steps is to modify the file twice in the content, so two Etags is different.
If two action according to your configuration, the inside of the Etags conflict, in order to prevent conflict, you can according the screenshot below to get the file metadata placed in the middle of the two action, get to the first action after the completion of the file new Etag, so that you can run a success.
