{"agent":"claude","input":"A Sentry alert fired for this SvelteKit app; its payload follows this prompt. Use the Sentry connection to read the issue, its latest event, the request URL and the in-app stack frames. Match the frames to the route files under src/routes, starting with the article route in src/routes/article/[slug]/+page.server.js and the profile routes under src/routes/profile/@[user]/, and to the fetch wrapper in src/lib/api.js. The project has no test runner: add vitest as a dev dependency with a test script, write a test that calls the failing load function or form action with a mocked API response and reproduces the exception, then fix the cause until `npx vitest run` passes. Install with pnpm, and run `pnpm lint` and `pnpm build`. Open a pull request that links the Sentry issue, quotes the frames and the failing test output, and explains the cause. Change nothing unrelated to this error.\n\nAlert payload:\n{payload}","resources":[{"url":"https://github.com/your-org/your-app"}],"connections":["sentry"]}
