Expected Behavior

The FTS should work across Python versions. If I run the FTS with Python 3.9 and retrieve features with Python 3.7, it should work.

Current Behavior

It fails with TypeError: an integer is required (got type bytes) error, due to dill. I think dill has trouble serializing across Python versions. See this and this for more details.
