Fixed in commit 31bc9b0. Added a sanitization step that replaces commas and spaces in the workloads input with hyphens before generating the cache key. Now "wasm-tools, maui" becomes "wasm-tools-maui" in the cache key, which is valid.

@copilot there is something missing, it seems that cache is not working, when running livecharts.yml, when the pack maui happens, it installs the maui workloads, then when we run ui tests for maui, it reinstalls again the maui workloads, it seems that the cache is ignored, we must be missing something

Fixed in commit 55f3e7e. The issue was that cache paths were using ~/.dotnet/ which doesn't exist - workloads are actually installed at $DOTNET_ROOT (C:\Program Files\dotnet on Windows, /usr/share/dotnet on Linux). Now the action dynamically detects the actual dotnet root path and caches the correct directories (sdk-manifests, packs, template-packs, metadata/temp).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• learn.microsoft.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
