Root Cause Analysis

This is not an azd CLI crash — it's a VS Code extension timeout.

The extension spawns azd show --no-prompt --cwd <dir> --output json with a hardcoded 20-second timeout (DefaultAzCliInvocationTimeout in azureDevCli.ts:14). When azd show takes longer than 20s — which is common when it makes Azure API calls, triggers extension auto-install, or runs on ARM64 Windows (this user's environment) — Node.js kills the child process with SIGTERM.

Error Chain

AzureDevCliApplication.getResults()
  → showProvider.getShowResults()
    → execAsync('azd', ['show', ...])
      → child_process.spawn(..., { timeout: 20000 })
        → (>20s) → Node.js sends SIGTERM
          → ChildProcessError: 'Process exited due to signal SIGTERM'

Recommended Fix

Increase the timeout for azd show calls in AzureDevShowProvider.ts to 120s. The 20s default is fine for quick commands (azd version, azd auth login --check-status) but too aggressive for azd show which makes ARM API calls.

Additionally, catch the SIGTERM case and show a user-friendly message instead of the raw ChildProcessError.

Key Files

• ext/vscode/src/utils/azureDevCli.ts:14 — DefaultAzCliInvocationTimeout = 20 * 1000
• ext/vscode/src/services/AzureDevShowProvider.ts:46-73 — spawns azd show
• ext/vscode/src/views/workspace/AzureDevCliApplication.ts:69-76 — triggers resolve

@raj-oo8 Could you provide more details about retro steps? Does it match with the Root Cause description?
