mistyPy import fails with python 3.5.5

[is-bibih]

When attempting to import the module (installed through pip), the following error appears:

File "/home/xxx/.pyenv/versions/3.5.5/lib/python3.5/site-packages/mistyPy/__init__.py", line 93, in populateImages
    for out in reply["result"]:
TypeError: string indices must be integers

I'm using Python 3.5.5, requests version 2.24.0 and websocket-client version 0.52.0. Should I switch to a different version of Python or requests?
