orientdb client version errors

OrientDB's Python client has been consistently broken for the past couple years. A newer fork (https://github.com/orientechnologies/pyorient/issues/42, https://github.com/brucetony/pyorient) claims to support 3.1.x, but using the 3.1.12 Docker image results in the below error:

Until official (or stable) maintenance of the pyorient project happens, Machina will have to continue to depend on an older version of OrientDB and another pyorient fork.
