[🐛 Bug]: Using Relay Feature in Grid 4 with Selenium Node Docker

[burakkaygusuz]

What happened?

The problem

I would like to configure 2 different relay using SE Node Docker via docker compose. Grid setup is successful but when I execute the test, I get the error as below:

Maven Surefire Plugin Log

org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: Could not start a new session. New session request timed out

Environment

• Appium version : 2.0.0-beta.43
• Appium drivers : UIAutomator2 v2.4.9
• Node.js version: 16.17.0
• Mobile platform/version under test: Android API 32 & Android API 33
• Real device or emulator/simulator: emulator

Server Configurations

appium1.yaml

server:
  port: 4723
  keep-alive-timeout: 80
  session-override: true
  use-drivers:
    - uiautomator2

appium2.yaml

server:
  port: 4724
  keep-alive-timeout: 80
  session-override: true
  use-drivers:
    - uiautomator2

Nodes

[server]
port = 5555

[node]
detect-drivers = false

[relay]
url = "http://host.docker.internal:4723"
status-endpoint = "/status"

[[relay.configs]]
max-sessions = 1
stereotype = '{"platformName":"android","appium:automationName":"UIAutomator2","appium:udid":"emulator-5554","appium:platformVersion":"12","appium:systemPort":"8101"}'

[server]
port = 5556

[node]
detect-drivers = false

[relay]
url = "http://host.docker.internal:4724"
status-endpoint = "/status"

[[relay.configs]]
max-sessions = 1
stereotype = '{"platformName":"android","appium:automationName":"UIAutomator2","appium:udid":"emulator-5556","appium:platformVersion":"13","appium:systemPort":"8102"}'

Configuration Steps to Reproduce

1 - Create and start the two virtual devices.

2- Start Appium servers

appium server --config /path/to/appium1.yml

appium server --config /path/to/appium2.yml

3- Execute the yml file

docker-compose -f docker-compose.yml up

When sending a request to get grid status info:

curl http://localhost:4444/status

{
  "value": {
    "ready": true,
    "message": "Selenium Grid ready.",
    "nodes": [

Can you share the complete logs? I mean, I cannot know what the issue is with just a single line. Right?
