Error Analysis:

• The success toast spy never fires after clicking Save, so the test times out waiting for toast.success().
• Appears to be timing/async ordering around updateActiveTemplateVersion completion or toast emission.

Root Cause Classification: Flaky test (toast not emitted / async timing)

Assignment Analysis:

• git log --oneline -10 --follow site/src/pages/TemplateSettingsPage/TemplateVariablesPage/TemplateVariablesPage.jest.tsx
  • 15a2bab1cd31a3b64844d3feb8b8835c4de3d871 feat: migrate from <GlobalSnackbar /> to sonner (#22258) (author: Jake Howell, GitHub: jakehwll)
• No newer test-specific commits found; recent toast migration likely affects this expectation.
