Hermes Agent's computer-use functionality on Linux, specifically its window enumeration process and integration with the browser extension via the gateway.

Technical Positioning

Ensuring robust and reliable cross-platform functionality for Hermes Agent, particularly its ability to interact with the desktop environment (window enumeration, screen capture, input) on Linux. The goal is to provide a seamless "computer-use" experience for agents, preventing crashes due to unexpected null values from window managers and maintaining the integrity of the browser extension's connection to the local Hermes runtime.

SaaS Insight & Market Implications

This issue reveals a critical stability flaw in Hermes Agent's `computer-use` functionality on Linux, specifically a `NoneType` error during window enumeration. This bug, linked to upstream Hermes Agent issues, causes crashes when X11 window managers return `null` values for `pid` or `window_id`. While `hermes doctor` reports healthy, the core agent's ability to interact with the desktop environment is compromised, blocking user adoption of the browser extension/gateway path. This directly impacts Hermes Agent's value proposition for automating computer-use tasks on Linux, highlighting a need for more robust input validation and error handling in core agent components to ensure cross-platform reliability and prevent user-facing failures.

int() argument must be a string, a bytes-like object or a real number, not 'NoneType'

chrome extension is installed as well but the gateway looks having issue : int() argument must be a string, a bytes-like object or a real number, not 'NoneType'

Any clue how to make it working ?

## Hermes Agent Issue Triage ## Summary Issue looks like a Linux gateway / browser-extension integration bug or setup-support case. The reported error, `int() argument must be a string, a bytes-like object or a real number, not 'NoneType'`, strongly suggests Hermes/gateway code is trying to cast a missing config/request value to `int()` instead of validating it first. ## Triage - Likely category: Bug / support triage - Area: Gateway + browser extension + computer-use on Linux - Platform: Ubuntu 24.04.4 LTS, `cua-driver 0.7.0` - Severity / risk: Medium - Blocks user from using the extension/gateway path. - No evidence of data loss or security exposure from the issue body. - The current report is not reproducible enough to confirm root cause. - Not enough evidence to assign this to `cua-driver`; `hermes computer-use doctor` is passing core checks. ## Questions / missing info Please ask for: - Exact Hermes version: `hermes --version` - B...

Thanks for the extra details — this now looks like the known Hermes Agent Linux `computer_use` window-enumeration crash rather than a Browser Extension pairing/API-server startup problem. What your logs already prove: - `hermes computer-use doctor` is healthy on your machine. - The Hermes API server is starting correctly and listening on `http://127.0.0.1:8642`. - The raw error, `int() argument must be a string, a bytes-like object or a real number, not 'NoneType'`, matches an upstream Hermes Agent issue where Linux/X11 window enumeration can return compositor/window-manager entries with `pid: null` or `window_id: null`. Relevant upstream tracking: - NousResearch/hermes-agent - NousResearch/hermes-agent The active upstream fix skips untargetable null window entries and keeps valid application windows, instead of letting one compositor row crash `computer_use` capture/focus. What would help us confirm 100% from your side: 1. Does the error appear immediately when clic...
