Creating a provider of ABC

[awaizman1]

Hi,

I'm trying to create a Dependency provider for some python interface I have in the form of abstract-base-class (ABC).
Trying creating the provider raises an error.
What is the correct way for achieving this?

# file testc.py

from abc import ABC

from dependency_injector import providers

class Base(ABC):
    pass

class Impl(Base):
    pass

p = providers.Dependency(Base)  # this line raises
p.provided_by(providers.Object(Impl()))

I get the following error:

Traceback (most recent call last):
  File "testc.py", line 13, in <module>
    p = providers.Dependency(Base)
TypeError: Argument 'instance_of' has incorrect type (expected type, got ABCMeta)

Thanks

Fixed in 3.23.1. It's already on the PyPI. You're welcome to upgrade.

Thanks for raising the issue.
