Cannot install EAMapReader-Slicer-4.11 extension

Problem report for Slicer 4.11.20200930 macosx-amd64

I am trying to install the following extension: https://github.com/stephan1312/SlicerEAMapReader#readme

Expected Behavior:

In the extension manager select “Install from file” and install the EAMapReader.zip file.

Actual Behavior:

Fails to install extension. Logs attached. I renamed the file “EAMapReader.zip” but still nothing. I moved all the files to my desktop and tried from there - no luck.
