# NousResearch/hermes-agent · SSE in-stream error status code classification fixes

## Open now

- Nothing open on GitHub.

These items address how numeric HTTP status codes embedded in in-stream SSE error objects are parsed and classified, including cases where status-less or numeric error codes were misidentified, leading to incorrect retry behavior or misleading error reporting.

## TL;DR

- 4 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 2 PR(s) closed without merging.
- A fix was merged to main in PR #121547. Verify it addresses your case.
- **Recommended:** read PR #121547 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-121547`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.50`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #121270: In-stream SSE error object's HTTP-status code is ignored: a 403 upstream ban is retried and reported as 'temporarily unavailable'
