'list' object has no attribute 'middlewares'

The following code raises the above error.

def auth_middleware(resolver, obj, info, **kwargs):
    value = resolver(obj, info, **kwargs)
    return value

@graphql_api.route('/graphql', methods=["POST"])
def graphql_server():
    success, result = graphql_sync(
        schema,
        request.json,
        middleware=[auth_middleware]
    )

I think this is causing the issue: https://github.com/mirumee/ariadne/blob/2d2184939bf469f3a607bf3e08f2f27ca0fa7421/ariadne/extensions.py#L29-L30

Looks like the documentation isn’t up to date or wrong since this is expecting an MiddlewareManager but the documentation shows a plain list. Or am I getting something wrong here?

Mhhh. So now I’m passing in MiddlewareManager([auth_middleware]) to graphql_sync, the error is gone but the middleware never gets called.

Edit: It looks like it has to be called like this, MiddlewareManager(auth_middleware, another_middleware, ...)

I’ve decided to re-do middlewares starting with Ariadne 0.17. middlewares option will now be:

• None
• List of middlewares
• A function returning None or list of middlewares

If you need custom middleware manager, it will be passable as middleware_manager_class option.
