[jira] [Commented] (NIFI-7728) FetchS3Object gets stuck with Key
cannot be empty
[ https://issues.apache.org/jira/browse/NIFI-7728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17189886#comment-17189886 ]
Kotaro Terada commented on NIFI-7728:
-------------------------------------
Hi,
We've been able to reproduce this issue, confirmed that other S3 processors (such as PutS3Object or DeleteS3Object ...) send such flowfiles to failure. Please let us work on it.
