In python 3.11.0 monitoring_v3 import is failing

When trying to run a simple script to list the services, the import fails due to an AttributeError in proto\enums.py file

• Python version: Python 3.11.0
• pip version: pip 22.3.1

^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'dict' object has no attribute 'index'

Facing this issue as well

I've found code in proto/enums.py:ProtoEnumMeta.__new__:

        if pb_options in attrs._member_names:
            idx = attrs._member_names.index(pb_options)
            attrs._member_names.pop(idx)

According to error and code, it looks like it was a list and now it's a dict, so we can fix it this way:

        if pb_options in attrs._member_names:
            attrs._member_names.pop(pb_options, None)

However, I still can't figure which package is it exactly

[eremeevfd]

It's a proto-plus package

[eremeevfd]

googleapis/proto-plus-python#326

There is even better fix there

Thanks for reporting this issue. I've published a pre-release version of proto-plus with the fix. https://pypi.org/project/proto-plus/1.22.2rc1/

The release will be published on Monday
