…atibility webpack-dev-server v5 removed the top-level `https` option (now nested under `server`) and replaced `onBeforeSetupMiddleware`/`onAfterSetupMiddleware` with `setupMiddlewares`. This caused a schema validation error on startup in microsites using backpack-react-scripts@11.2.3. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

Note
Copilot couldn't run its full agentic review because no GitHub Actions runner was available. Make sure your repository has a runner available to run Copilot's review, or add a copilot-setup-steps.yml file specifying one with the runs-on attribute. See the docs for more details.
Updates react-scripts’ webpack-dev-server configuration to be compatible with webpack-dev-server v5 by migrating removed v4 options/hooks to their v5 equivalents.
Changes:
- Replaced removed top-level
httpsdevServer option with v5serveroption, mappinggetHttpsConfig()output appropriately. - Migrated v4
onBeforeSetupMiddleware/onAfterSetupMiddlewarehooks to the v5setupMiddlewaresAPI.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

backpack-react-scripts@11.2.3pulled inwebpack-dev-server@^5.2.2butwebpackDevServer.config.jsstill used v4 APIs, causing this schema validation error on startup in profile, login and subscription-microsite:Those consumers worked around it by either reverting to
11.2.2(profile) or overriding wds back to v4 (login, subscription-microsite). Once this is released as11.2.4they can bump to the fixed version and remove their workarounds.Fixes GATE-1102
TESTING:
Tested locally by packing the patched version with
npm packand installing the tarball directly intoprofile/client. Ran client dev server and it started successfully with no schema validation errors🤖 Generated with Claude Code
