From Linux (OS Fedora-42) plateform, mongod running version 8.1.
User as role admin or even root, replicaSet indicated in the uri to connect, connection is fine.
Call of client.ListDatabaseNames with nil filter and what ever the option is (test long time through your official AI online), returnb all the time an empty . It should return the list of database names.
The mongosh show trhem, the Compass shell too, and the direct call command:
dbs, err := client.ListDatabaseNames(context.Background(), nil, options.ListDatabases().SetAuthorizedDatabases(true))
show also the databases list.
It is definitely an issue.
Sorry to discover that you decide also to NOT provide an issue access from your github repository, that is boring. I hope you will be more friendly and open to any feedback to come without to push your users to loose a lot of time just to communicate something to you.
good luck.
Not only ListDatabaseNames has bug and return nil document, but also ListCollectionNames call from an opened database return nil document. I am able to show evidence and use case text code.
It is incredible there is no issues places in your github repo to publicate an issue notice.
The commercial chat by the time is working perfectly.
I have to build web-site for sale to clients, but i scare with Atlas company to just paid to speak with commercial and loose time and money to try to test your code without any return in a forum.
