@venkii

You need to login to your secured NiFi-Registry and make sure all your NiFi nodes have been authorized for both the following "Special Privileges":

1. "Read" for "Can Manage Buckets"
2. "Can proxy user requests"

Click on wrench icon in upper right corner to manage your users in NiFi-Registry.

Then find your NiFi nodes in the list of USERS and click on the "manage user" pencil icon to the far right side.

Hope this helps,

Matt
