Fix: PowerShell code snippets not appearing

Hi @merill 👋

Fixes #8

Problem

PowerShell code snippets fail to render in the Graph X-Ray DevTools panel. Other languages (C#, Python, Go, JavaScript, Java) work correctly.

Root cause: Microsoft's DevX snippet API (devxapi-func-prod-eastus.azurewebsites.net) returns HTTP 500 for all PowerShell snippet generation requests. This is a server-side regression — the extension correctly calls the same endpoint and parameters used by the official Microsoft Graph Explorer, but the API fails specifically for ?lang=powershell.

Since the extension has no control over the external API, this PR adds a client-side fallback.

Solution

When the DevX API fails for PowerShell (HTTP error or network failure), the extension now generates idiomatic PowerShell snippets locally using Invoke-MgGraphRequest from the Microsoft Graph PowerShell SDK.

What changed (src/common/client.js)

• generateLocalPowerShellSnippet() — Produces complete PowerShell snippets with Import-Module, Connect-MgGraph, and Invoke-MgGraphRequest
• formatPowerShellValue() — Recursively converts JSON request bodies into PowerShell hashtable literals (nested objects, arrays, $true/$false/$null, numbers, strings with proper escaping)
• buildDevxUri() — Extracted and simplified the DevX API URL construction logic
• getSnippetFromDevX() — Refactored main function with a single fallback path (replaces duplicated error handling)
• Bug fix: response.text() was missing await on the success path

What didn't change

• Other languages continue using the DevX API as before
• No UI changes — snippets render in the same SyntaxHighlighter component
• If/when the DevX API is fixed, PowerShell will automatically use it again (fallback only fires on failure)

Example output

For a GET /v1.0/me request, the fallback generates:

Import-Module Microsoft.Graph

Connect-MgGraph

Invoke-MgGraphRequest -Method GET -Uri "https://graph.microsoft.com/v1.0/me"

For a POST with a JSON body:

Import-Module Microsoft.Graph

Connect-MgGraph

$params = @{
	displayName = "Test User"
	accountEnabled = $true
	passwordProfile = @{
		forceChangePasswordNextSignIn = $true
		password = "xWwvJ]6NMw+bWH-d"
	}
}

Invoke-MgGraphRequest -Method POST -Uri "https://graph.microsoft.com/v1.0/users" -Body ($params | ConvertTo-Json -Depth 10) -ContentType "application/json"

Evidence

Before (PowerShell selected — no snippet rendered)

After (PowerShell selected — fallback snippet rendered)

Code Review

This pull request increments the project version to 1.0.6 and introduces a local fallback mechanism for generating PowerShell snippets in src/common/client.js when the DevX API is unavailable. The review feedback identifies several opportunities to improve the robustness of the generated PowerShell code, including quoting hashtable keys to support OData attributes, escaping special characters in strings to prevent unintended interpolation, and ensuring multi-line raw bodies are correctly commented out in fallback scenarios.

@jorgeasaurus Tx a lot for the PR.

I've already merged it. Are you making any new updates?

[jorgeasaurus]

You're welcome. No other changes at this time.

[merill]

Awesome tx. I'm making some other updates too to improve experience.

Tx a lot for the Firefox PR too. I'll test it and include it in the list of supported browsers.
