Flask-APIspec and flask-injector with inject decorator doesn't work together for views.

[pratik261199]

I have upgraded my packages to:
flask-2.2.2
injector-0.20.1
Flask-injector-0.14.1
apispec-6.0.2
flask-apispec-0.11.4

I'm using Flask-apispec to auto-generate api documentation, and I'm using injector library. both independently works well in my code but when I use them together, it throws the error missing positional argument.
I tried to debug the code, in stack trace, it skips the inject decorator.

Here is a sample code

import marshmallow as ma
from flask_apispec import doc, marshal_with, use_kwargs
from injector import inject
from flask_injector import FlaskInjector
from injector import inject, singleton

def configure(binder):
    binder.bind(
        str,
        to="MyCat",
        scope=singleton,
    )


class Pet:
    def __init__(self, name, type):
        self.name = name
        self.type = type


class PetSchema(ma.Schema):
    name = ma.fields.Str()
    type = ma.fields.Str()




###

import flask
import flask.views

from flask_apispec import FlaskApiSpec, MethodResource

app = flask.Flask(__name__)
docs = FlaskApiSpec(app)


@doc(
    tags=['pets'],
    params={'pet_id': {'description': 'the pet name'}},
)
class CatResource(MethodResource):
    @inject
    def __init__(self, pet_name: str):
        self.pet_name = pet_name
        super().__init__()
    @marshal_with(PetSchema)
    def get(self, pet_id):
        return Pet(self.pet_name, 'cat')

    @marshal_with(PetSchema)
    def put(self, pet_id):
        return Pet('calici', 'cat')

app.add_url_rule('/cat/<pet_id>', view_func=CatResource.as_view('CatResource'))

# registering view
docs.register(CatResource, endpoint='CatResource')
FlaskInjector(app=app, modules=[configure])

if __name__ == '__main__':
    app.run(debug=True)

Everything works well if I comment out the "docs.register(CatResource, endpoint='CatResource')"'
Note: Everything was working fine before upgrading libraries to the latest
