I got error when I try to use the appium inspector.

[foxmari]

Hello.
Please help me!

I am trying to start the appium server with docker on MacOS （Monterey）and connect it to the appium inspector started on the host PC.
When I start the appium server and click the start session button on the appium inspector, I get this error

### I am excerpting errors that seem particularly relevant, but I will attach the full log later (log.txt)

(The actual udid is entered as the ID confirmed by the adb devices command, but it is replaced with dummy data when taking this log file.)

Here is the docker-compose file I used to start this container.

version: '3'
services:
  appium:
    image: appium/appium
    container_name: appium_container
    environment:
      - ADB_SERVER_SOCKET=tcp:host.docker.internal:5037
      - ANDROID_ADB_SERVER_ADDRESS=host.docker.internal
      - ANDROID_ADB_SERVER_PORT=5037
      - ANDROID_HOSTNAME=host.docker.internal:8200
    volumes:
      - /dev/bus/usb:/dev/bus/usb
    ports:
      - "4723:4723"
      - "8200:8200"
    privileged: true
    extra_hosts:
      - "host.docker.internal:host-gateway"

Attached is a screenshot of the appium inspector settings screen.

(The actual udid is entered as the ID confirmed by the adb devices command, but it is replaced with dummy data when taking the screenshot.)

And, the adb devices command works inside the container, but will not work if the environment variable is not set.
ADB_SERVER_SOCKET=tcp:host.docker.internal:5037

Incidentally, if I enter /wd/hub in the Remote Path on the configuration screen of the appium inspector to start a session, a 404 error is returned.

Docker host OS is macOS (Monterey),My docker runtime is colima.

I think I have specified the necessary parameters as much as possible, but I think they are not enough.
Can I use this container with a MacBookPro?
Please help me...!

This is my first time writing a github issue, so I apologize if I am rude.
Thank you.

If Appium client code encounters difficulties connecting to the Appium server during testing, ensure that the host in the capabilities section of the client code is set to host.docker.internal.
