In release 0.1.7, atlasclient.models.EntityUniqueAttribute raised an exception when reading the entity attribute.

I tested atlasclient 0.1.7 and 1.0.0 together with a bare Atlas server 2.0.0 running in a docker container, and in such configuration the atlasclient.base does not raise the Missing attr EntityUniqueAttribute exception.

This means atlasclient>0.1.3 is not compatible with Atlas 0.8.0 which is delivered with our HDP 2.6.5 cluster.

Do you have the same issue with pyatlasclient which is a fork of atlasclient and more actively updated?

I have the same issue running pyatlasclient 1.0.3 with Atlas server 2.0.0. It works fine when running the code on my local Mac with Python 3.6.4 (Anaconda distro), while it is logging the following messages when running in a docker container (python:3.6-alpine): f2020-03-19 10:28:43,731 - Missing attr EntityUniqueAttribute: searchParameters
