[Python] Second-order decorators with access in functions arguments

So I am a bit confused with this and I have tried a lot of things but nothing worked so far. I have seen the similar questions but still couldn't make it work.

My function

import azure.functions as func
from pydantic import ValidationError
from utils.auth import with_auth, decor2
import logging

project_bp = func.Blueprint()


@with_auth
@project_bp.route(route="project", auth_level=func.AuthLevel.ANONYMOUS, methods=["GET"])
def project(req: func.HttpRequest) -> func.HttpResponse:
try:
return func.HttpResponse(f"Hello all possible worlds! ---- --- -- *", status_code=200)

except ValidationError as e:
return func.HttpResponse(f"Validation error: {e}", status_code=400)



def with_auth(func):
# Function runs until here
# @wraps(func)
def wrapper(*args, **kwargs):
# Access the request object (req) here
req: az.HttpRequest = kwargs["req"]
for k in req.headers.values():
print(k) # Prints nothing...

# If authenticated, call the original function
return func(*args, **kwargs)

return wrapper



Only if I change the decorator order it works, but I think it's better to have it above the router as Flask endpoints. What am I missing?

Tried a lots of examples from here, yet, none of them seemed to work properly.
