Middleware file does not exist

[sybanyt]

I am unable to start up the container. I am following the traefik2 guide and starting with only traefik. In the docker logs I am getting the error:
2022-04-24T23:14:32.900304553Z time="2022-04-24T23:14:32Z" level=info msg="Configuration loaded from flags."
2022-04-24T23:14:35.508591200Z time="2022-04-24T23:14:35Z" level=error msg="middleware "chain-oauth@file" does not exist" entryPointName=https routerName=traefik-rtr@docker

I have created a middelwares.toml file in the traefik2/rules folder with the content below:
[http.middlewares]
[http.middlewares.chain-oauth]
[http.middlewares.chain-oauth.basicAuth]

users = [

"user:$apsdfswWvC/6.$E3FtsfTntPC0wVJ7IUVtX1",

]

  realm = "Traefik2 Basic Auth"
  usersFile = "/shared/.htpasswd" #be sure to mount the volume through docker-compose.yml

Figured it out. I was creating the middlewares.toml file in the wrong directory
