The upgrade is not finished yet.

Packages that are not marked as compatible with react 18 or related upgrades (warnings using yarn install):

• connected-react-router
• react-dates
• react-helmet
• react-hot-loader
• react-lazylog
• react-split-pane
• react-table-6
• react-tabs
• redoc
• reactstrap (upgrading to 9.x.x involves https://github.com/reactstrap/reactstrap/blob/master/CHANGELOG.md#900-2021-10-27)

With the current state I got a usable application with some warning/errors:

• Warning: Encountered two children with the same key, maven-metadata.xml. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.
  Warning: Failed prop type: Invalid prop children supplied to ErrorBoundary. (react-hot-loader)
• Error: Need to retrieve or renew Taskcluster credentials before action can be performed. (getCredentials taskcluster.js:93)

Some tests fails on those modules:

• tests/ui/perfherder/graphs-view/graphs_view_test.jsx
• tests/ui/perfherder/graphs-view/test_data_modal_test.jsx
• tests/ui/perfherder/selector_card_test.jsx
