# NousResearch/hermes-agent · Classifying status-less streaming provider errors for failover

## Open now

- Nothing open on GitHub.

The members concern streaming provider errors that arrive without a status_code (for example LM Studio Jinja render errors) and so bypass the 400 classifier, with one issue describing the turn ending silently without failover. The PRs propose classifying these errors as format_error so failover can apply; one also mentions body status codes and auxiliary fallback, and one is noted as superseding an earlier PR.

## 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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

- #62662: Streaming provider errors with no \`status_code\` (e.g. LM Studio Jinja render errors) bypass the 400 classifier and never fail over — turn dies silently
