Cannot add middleware after an application has started

[am077]

I'm trying to set up basic auth but I get this error. My main.py only contains basic auth code.

Using,

Pixi 0.38
writer 0.8.1

Code :

import writer as wf
import webapp.handlers as hd

import os
import writer.serve
import writer.auth

auth = writer.auth.BasicAuth(
    login='test',
    password='test',
)

writer.serve.register_auth(auth)

Error :

Pixi task (run): writer run .

My bad, I configured it in server_setup.py file. Now it works.
