# NousResearch/hermes-agent · Vision analyze 400 errors and image handling hardening

## Open now

- Nothing open on GitHub.

Two of three members concern the vision_analyze tool: one reports 400 'Invalid request data' errors on valid local image paths, and another proposes rejecting oversized images, handling file:// URIs, and improving 400 error messages. The third is a broader batch PR that touches vision hardening alongside unrelated items (MCP names, zombies, test isolation), so it only partly fits the theme.

## 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 #7654. Verify it addresses your case.
- **Recommended:** read PR #7654 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict
