# NousResearch/hermes-agent · Fix missing session header on one-shot requests

## Open now

- Nothing open on GitHub.

These issues and PRs address a bug where sessionless one-shot calls (such as commit message generation) were producing 400 \`MissingSessionID\` errors due to a missing \`x-opencode-session\` header. The fixes synthesize or preserve an ephemeral session header for these stateless requests across multiple layers.
