# NousResearch/hermes-agent · Fix parsing of JSON-stringified tool_call batch envelopes

## Open now

- Nothing open on GitHub.

These issues and pull requests all address the same bug: when a model emits a tool_call batch envelope as a JSON string rather than a parsed array, it is incorrectly rejected with a misleading error, leading to tool-call loops. The members focus on parsing that stringified envelope correctly.

## TL;DR

- 5 member(s): 0 open issue(s), 1 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 #114775. Verify it addresses your case.
