time="May 30 08:13:45" level=info msg="Loading existing bundle: bundle.zip" 
time="May 30 08:13:45" level=info msg="----> Loading bundle: bundle.zip" 
time="May 30 08:13:45" level=info msg="----> Using bundle: bundle.zip" 
time="May 30 08:13:45" level=info msg="Loading module: 'main'"

    },
    "strip_auth_data": false
}

and my main.py is :

from tyk.decorators import *

@Pre
def MyAuthMiddleware(request, session, spec):
    auth_header = request.get_header('X_remote_addr')
    request.add_header("pyTest", auth_header)
    request.add_header("pyTest2", "hello!")
    print("hello!!")
    return request, session

there is no pyTest header in my upstream request
i have no idea what have i done wring
ps: all are containers and /var/log has no sign of tyk logs

EDIT: i have set enable_coprocess_auth to true but it still doesnt work

You should set enable_coprocess_auth to true, see our official guide.
