{"agent":"claude","input":"A Sentry alert fired for this Wagtail site; the payload follows this prompt. Use the Sentry connection to read the issue, its latest event, the request URL, the tags and the in-app frames. Find the page model, view or template the frames point at. Write a WagtailPageTestCase in bakerydemo/<app>/tests/ that builds the page tree in setUpTestData, requests the same URL and asserts the response the route should give, or the query count for a performance issue; confirm it fails with the same error. Fix the cause in the model, view or template rather than hiding it in the template, add a migration if a field changes, run ./manage.py test with bakerydemo.settings.test, ./manage.py makemigrations --check and make lint-server, and open a pull request that links the Sentry issue, quotes the frames and the failing test output, and explains the cause. Do not change the demo fixture unless the fix needs it. If it does not reproduce, stop and report what you tried.\n\nAlert payload:\n{payload}","connections":["sentry"],"resources":[{"url":"https://github.com/your-org/your-app"}]}
