Additional Context

The diagram renders correctly on the mermaid live editor.
I could not check right not, but might it be a mermaid version error? If the class diagram requires mermaid 10.2.0 version or later and Github uses mermaid 10.1.0 (I took random version numbers for this example), an error would be triggered

If there is an unsupported feature in the diagram, maybe we could remove it from the main readme till github updates mermaid.
