The service errors@docker does not exist

Hi,
I'm sorry if this is covered somewhere, but I could not find information on it anywhere. It's probably just a typo or something on my side, but after looking for an hour, I thought, I might as well post here. I am using Tarampampam's error pages and the logs return the following:

traefik                | time="2023-03-31T14:52:32Z" level=info msg="Configuration loaded from file: /etc/traefik/traefik.yml"
traefik                | time="2023-03-31T14:52:36Z" level=error msg="middleware \"error-pages-middleware@docker\" does not exist" routerName=traefik@docker entryPointName=web
traefik                | time="2023-03-31T14:52:41Z" level=error msg="the service \"errors@docker\" does not exist" entryPointName=web routerName=traefik@docker
traefik                | time="2023-03-31T14:52:41Z" level=error msg="the service \"errors@docker\" does not exist" entryPointName=web routerName=error-pages-router@docker

Lastly, this is my docker-compose.yml file.

version: '3'

Share your Traefik static and dynamic config.

Dynamic is already there. Static is here:

global:
  checkNewVersion: true
  sendAnonymousUsage: false  # true by default

# (Optional) Log information
# ---
# log:
#  level: ERROR  # DEBUG, INFO, WARNING, ERROR, CRITICAL
#   format: common  # common, json, logfmt
#   filePath: /var/log/traefik/traefik.log

# (Optional) Accesslog
# ---
# accesslog:
  # format: common  # common, json, logfmt
  # filePath: /var/log/traefik/access.log

# (Optional) Enable API and Dashboard
# ---
api:
  dashboard:false  # true by default

# Entry Points configuration

Usually labels use a dash, have you tried that?

version: "3"
services:
  my-container:
    # ...
    labels:
      - traefik.http.routers.my-container.rule=Host(`example.com`)

Just tryed that, changes nothing :(.

You use providers.file.directory, are there other (old) config files in the directory?

Nope, only acme.json. Not sure why I put that there, must have been copied from somewhere.
