{"agent":"codex","input":"A Sentry alert fired for this Go service; its payload follows this prompt. Use the Sentry connection to read the issue, its latest event, breadcrumbs and the stack frames with their package paths. Read the functions the frames name, starting with RefreshFeed in internal/reader/handler/handler.go and the response handler in internal/reader/fetcher/response_handler.go. Add a regression test, as a new row in the package's existing table-driven _test.go file where there is one, otherwise a new _test.go file using httptest, that reproduces the error. Fix the code until the test passes, then run `make test` and `make lint`. Open a pull request that links the Sentry issue, quotes the frames and the failing test output, and explains the cause. If the cause is outside this repository, open no pull request and say what you found.\n\nAlert payload:\n{payload}","resources":[{"url":"https://github.com/your-org/your-app"}],"connections":["sentry"]}
