# NousResearch/hermes-agent · Handling None message content in agent codebase

## Open now

- Nothing open on GitHub.

These issues and pull requests address a bug where message content fields can be None (particularly for tool-call assistant messages), causing crashes such as TypeErrors in the context compressor and potentially other areas of the codebase.

## TL;DR

- 6 member(s): 0 open issue(s), 2 closed issue(s), 0 open PR(s), 1 merged PR(s), 3 PR(s) closed without merging.
- A fix was merged to main in PR #277. Verify it addresses your case.
- **Recommended:** read PR #277 (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: `partially_resolved` · deciding PR(s): `pr-277`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.29`: 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

- #211: Context compressor crashes with TypeError when message content is None
- #276: msg.get("content", "") returns None for tool-call assistant messages across codebase
