injector._BindingNotYetAvailable: name 'Response' is not defined

[jsr1337]

Hello,
based on code from this post: #40 injector throws the above error. My code is almost identical, the only difference is flask_restful instead of flask_restplus:

from flask import Flask
from flask_restful import Api, Resource
from flask_injector import FlaskInjector, inject, singleton

app = Flask(name)
app.secret_key = "123"
api = Api(app=app)

class MyConf():
def init(self, val: int):
self.val = val

class MyApi(Resource):
@Inject
def init(self, conf: MyConf, **kwargs): # <- here just added **kwargs to receice the extra passed api parameter
self.val = conf.val
# Don't know if really needed
super().init(**kwargs)

def get(self, conf: MyConf):
    return {'x': conf.val}, 200

api.add_resource(MyApi, '/myapi')

def configure(binder):
binder.bind(
MyConf,
to=MyConf(456),
scope=singleton
)
# No need to bind the resource itself
#binder.bind(
# MyApi,
# to=MyApi(myConf)
#)

FlaskInjector(app=app, modules=[configure])

app.run(port=555, debug=True)

Am I doing something wrong here or this is a bug?
My setup:
Flask==2.0.1
Flask-HTTPAuth==4.4.0
Flask-Injector==0.12.3
Flask-JWT==0.3.2
Flask-RESTful==0.3.9
typing-extensions==3.7.4.3
typing-inspect==0.6.0
injector==0.18.4

I have the same error (Python 3.9 x64, Flask v2.0.1, Flask-Injector v0.12.3)

[ghostman2013]

My code that worked on older versions of Flask-Injector:

def create_app(testing: bool = False) -> Flask:
    app = Flask(__name__)
    config_app(app, testing)
    db.init_app(app)
    migrate.init_app(app, db)
    router.init_app(app)
    CORS(app)    
    # Setup injector
    injector = Injector([AppModule(app.config)])
    FlaskInjector(app=app, injector=injector)
    return app


class AppModule(Module):
    config: Dict[str, Any]

    def __init__(self, config: Dict[str, Any]):
        self.config = config

    def configure(self, binder: Binder):
        dao = Dao(db.session)
        app_path = PathService(self.config)
        notify = NotifyService(self.config)
        binder.bind(Dao, to=dao, scope=request)
        binder.bind(PathService, to=app_path, scope=request)
        binder.bind(NotifyService, to=notify, scope=request)

And base REST-resource:

class BaseResource(Resource):
    dao: Dao
    path: PathService

    @inject
    def __init__(self, dao: Dao, path: PathService) -> None:
        super(BaseResource, self).__init__()
        self.dao = dao
        self.path = path

What's wrong with this code? Unfortunately, debugging didn't help me. I found that the error happens in get_type_hints() function in injector module but I still can't get a reason of this error and how to fix it.

Error:

name 'Response' is not defined

Hi,
See #65

TL;DR : Issue with Flask > 2 using werkzeug > 2

[jstasiak]

Fixed in 0.13.0, thank you for the report.

Hello. Is this error fixed?

I have the same error

    raise _BindingNotYetAvailable(e)
injector._BindingNotYetAvailable: name 'Response' is not defined

Same here. I use

flask==2.1.1
flask-injector==0.13.0

I don't have Werkzeug as a dependency. Any advice?

We have downgraded Flask version to <2.0.0, it helped. Unfortunately, it was a radical way that may not suit for you. I don’t work with Flask for few months already, so I don’t know if the situation was changed.

Thanks for the reply. Unfortunately I don't think this will be an option for me.

I worked around the issue by replacing the dependency injection container.
