Allow Bundles in a Bucket to be Overwritten
To allow released bundles in a bucket to be overwritten, select the "Allow bundle overwrite" checkbox.

Currently, the only supported bundle type is a NiFi Archive (NAR). By default, buckets do not allow the re-release of released NARs. This setting explicitly allows the same version of a NAR to be uploaded to a bucket.
For more information on bundles, see the Manage Bundles section.
