Seen on macOS Sequoia 15.7.2 . Probably bug in Bun. writing directly to process.stderr works around it. Tested with Bun 1.3.4. The bug is only seen when process stderr is piped to another process such as tee like bun run dev -- serve --port 0 --print-logs --log-level INFO 2>&1 | tee -a test.log And then sending api request to trigger error logs
