neo4j.exceptions.ClientError: No write operations are allowed directly on this database. Writes must pass through the leader. The role of this server is: FOLLOWER

A funny one:

• We have a 3-node causal-clustered neo4j setup
• I’ve changed the routing protocol to be bolt+routing
• We’re using Neomodel with @db.transaction

We’re getting intermittent errors as per the issue title - i.e. it’s trying to write to a follower node, and presumably bolt+routing isn’t sending the transaction to the leader. Am I missing something? Is it that if the first interaction with the database is a read, that it opens the transaction on a follower node? Can I force it to the leader for every transaction?

@robertlagrant Thank you for your response, I think that the discussion with @mvanderkroon on the pull request was very informative about the specifics.

@aanastasiou I believe so. I have forked the repo, made the necessary changes and would be quite happy to issue a pull request. Should I point it to your master branch?
