# NousResearch/hermes-agent · Handling SSE errors lacking HTTP status codes

## Open now

- Nothing open on GitHub.

These items address a gap where structured errors arriving in-stream (without an accompanying HTTP status code) are not properly classified or caught by the auxiliary fallback mechanism. The work involves detecting and handling such statusless provider errors in the agent and auxiliary fallback logic.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.67`: 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.
