BIP7001
Severity
20 : Error
Message
ACL already exists for topic <insert_0> and principal <insert_1>.
Explanation
The broker received a request to create an ACL which already exists.
Response
You must use change or delete to act on the existing ACL or respecify the topic or the principal to create a new ACL entry. If you don't expect this ACL to exist, check that the ACL has not already been created by another user, and that you have deployed any changes you wish to make.
