Summary
res.end(...)instead of writing without closing the response.Root cause
The
/metrics/prometheusroute wrote the metrics payload but left the HTTP response open, causing clients likecurlto receive data and then hang until timeout.Impact
Metrics scrapes now complete normally while preserving the same response body and content type.
Validation
npm testnpm run typecheck
