[BUG] Exception on document generation

[phil65]

mkapi can crash for some specific classes on document generation. Exception gets thrown in core/docstring.py:194 and core/object.py:133:

Can fix that by replacing the line with:

try:
    objs = obj.mro()[1:-1]
except TypeError:
    objs = obj.mro(type)[1:-1]

but not sure if that is the best fix.

For me it happened for a class inherited from QtCharts.QAbstractSeries (https://pypi.org/project/PyQtChart/)

This here might be a similar issue, from another project: https://github.com/agronholm/sphinx-autodoc-typehints/issues/73

I tried to fix this issue but I'm not sure if the error doesn't happen in your package. So could you please clone the repository and build your documentation?

[phil65]

No exception anymore, but it only builds some few md/html files, not the complete package.

Thank you for your cooperation. Now Version 1.0.11 is available.
