Suggested next step

This is a genuine product bug: after clicking "Create account," the app calls `GET /api/profile?name=Ava%20Chen`, which returns a 404 (likely an HTML error page, since the JSON parse error says "The page c..."), so the profile fetch fails and the code in `app.bundle.js` (line 1, function `r`) throws `Cannot read properties of null (reading 'value')` when it tries to read a field from the missing profile data — this leaves the welcome message never rendered, causing Step 6's assertion to fail. Next action: check the `/api/profile` route/handler on the backend to see why it's returning 404 for a newly created user instead of the profile JSON (e.g., route not registered, or account creation not persisting before the profile fetch fires).

This step's screenshot changed noticeably from the previous run of this flow. Could be a layout shift, a broken image, a font failing to load, or an intentional design change. Compare the screenshots on the report to tell which.

low regression

Step 6 (assert) is flaky, passed only 0 of the last 1 runs before this one

This step (a welcome message greeting the new user by name) hasn't been reliably passing even before this run, so this failure is more likely a flaky dependency or unstable test data than a new break. Worth checking, but probably not a code... (click to expand)

Step 6 (assert) looks 6.1% different from moments ago

medium perf

Step 6 (assert) took 13.3s, up from 2.6s moments ago

This step has gotten noticeably slower than the previous run of this flow. Could be a new slow query, a bigger payload, or a third-party dependency slowing down.
