Error Message

  1. The build fails with the error: 'rm' is not recognized as an internal or external command. It fails with the error as the following: I prefer not to upload the full debug report for privacy reasons. However, the core issue is a platform compatibility error during the web UI build process.

Additional Logs / Traceback (optional)

Root Cause

When attempting to build the Web UI (via hermes dashboard or manual build), the process fails on Windows because the build script uses the Unix-specific rm command to clean directories.

Fix Action

Fixed

PR fix notes

PR #25090: fix(web): use Node.js for sync-assets instead of Unix rm/cp

Description (problem / solution / changelog)

Summary

sync-assets used Unix rm which is not available on Windows CMD/PowerShell, causing the web UI build to fail with 'rm is not recognized'.

Replace with a small Node.js script (web/scripts/sync-assets.js) that uses Node.js built-in fs APIs for cross-platform file operations.

Changes

  • web/scripts/sync-assets.js (new): ESM script that replicates the sync-assets logic
  • web/package.json: Updated sync-assets script to call node scripts/sync-assets.js

Closes #25073

Changed files

  • web/package.json (modified, +1/-1)
  • web/scripts/sync-assets.js (added, +34/-0)

Code Example

I prefer not to upload the full debug report for privacy reasons. However, the core issue is a platform compatibility error during the web UI build process.

Bug Description

When attempting to build the Web UI (via hermes dashboard or manual build), the process fails on Windows because the build script uses the Unix-specific rm command to clean directories.

Steps to Reproduce

  1. Run hermes dashboard in Powershell
  2. The build fails with the error: 'rm' is not recognized as an internal or external command.

Expected Behavior

The process should have built a web dashboard.

Actual Behavior

It fails with the error as the following: <img width="822" height="135" alt="Image" src="https://github.com/user-attachments/assets/3b175717-9044-429e-b7ab-36a96ca50504" />

Affected Component

Tools (terminal, file ops, web, code execution, etc.)

Messaging Platform (if gateway-related)

No response

Debug Report

I prefer not to upload the full debug report for privacy reasons. However, the core issue is a platform compatibility error during the web UI build process.

Operating System

Windows 11

Python Version

3.12.10

Hermes Version

0.13.0

Additional Logs / Traceback (optional)

Root Cause Analysis (optional)

I think that's because Powershell doesn't recognize the rm command, unlike Unix-like system. When I run it on Git Bash, everything goes well.

Proposed Fix (optional)
