Sauce Labs dropped Appium 'stable' version, breaking metrics tests

[antonis]

Description

The performance metrics tests (metrics (legacy, android), metrics (legacy, ios), metrics (new, ios)) are failing because Sauce Labs has removed the stable Appium version.

Error

StartupTimeTest > startup time() FAILED
    org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: 

    The Appium version 'stable' is not available. If it previously worked for you, it might be that we stopped supporting 
    this specific Appium version. Visit https://docs.saucelabs.com/mobile-apps/automated-testing/appium/appium-versions/#end-of-life 
    for more details on our Appium versions end-of-life strategy. 
    Please choose one of the following available versions: 
    appium2-20250501, appium3-deque-accessibility, appium3-2026-01, appium2-20250901, 
    appium3-2025-10, appium2-2025-09, appium2-deque-accessibility, 1.22.2, appium2-20250101, 1.22.1, latest

Impact

• Affects all branches, not just PRs — confirmed by re-running a previously passing job on main: https://github.com/getsentry/sentry-react-native/actions/runs/23201803389/job/67554013713
• The appiumVersion: stable is configured in the external action getsentry/action-app-sdk-overhead-metrics, not in this repo.
• Failing CI jobs:
  • metrics (legacy, android)
  • metrics (legacy, ios)
  • metrics (new, ios)

Fix

Update the Appium version in getsentry/action-app-sdk-overhead-metrics from stable to latest (or a specific version like appium2-20250901).

This was identified on the latest JS bump were all metrics checks failed. Verified the change by also rerunning a check on main that was passing a few hours ago https://github.com/getsentry/sentry-react-native/actions/runs/23201803389/job/67554013713
