---------------------------------------------------------------
Just to clarify, it is due to (in my DSE 4.8.6):
{code:title=DSE/resources/cassandra/lib/cassandra-driver-internal-only-2.7.2.zip/cassandra-driver-2.7.2/cassandra/cluster.py:2147|borderStyle=solid}
self_weakref = weakref.ref(self, callback=partial(_clear_watcher,
weakref.proxy(connection)))
{code}
Specifically, {{callback=}} is what is producing that error.
