[BUG] Bolt Hello message response doesn't contains "server"

[stefanak-michal]

Memgraph version 2.3.1

Environment Windows, Docker, PHP Bolt library

Describe the bug After connecting to memgraph over bolt first message is "hello" to login into. Server response for this message should be map with keys "server" and "connection_id" (optional "hints"). Currently response contains only "connection_id".

To Reproduce Steps to reproduce the behavior:

1. Connect to database over bolt and run hello message
2. Analyze response

Expected behavior Response has to contain key "server". Missing key "server" have to contain server agent string identifier like "memgraph/2.3.1".

Hi, I am Benjo from discord! Thanks for reporting this, however this is not a bug in our implementation, more likely a bug in our documentation. If you check our configuration options for Bolt, you can see the --bolt-server-name-for-init option: "Server name which the database should send to the client in the Bolt INIT message.". Our documentation is unfortunately not clear, because if you don't specify any name, then we won't send the "server" field of the SUCCESS message.

However I will leave this issue open until we fix the documentation.

Why you don't have default value?

I have put this task into the backlog.

Hi, +1 on this issue. I was unable to use python neo4j driver, unless I add --bolt-server-name-for-init=Neo4j/4.4.0 to the config. Is there any reason for this not to be the default?
