PowerShell 7.3 - Difficulty Parsing JSON from a REST API Response with Nested Structures

PowerShell JSON REST API

I'm stuck trying to Quick question that's been bugging me - I'm working with PowerShell 7.3 to retrieve data from a REST API that returns a complex JSON structure. However, I'm having trouble accessing certain nested properties in the JSON response. The API returns a response like this: ```json { "data": { "items": [ { "id": 1, "name": "Item 1", "details": { "description": "First item description", "tags": ["tag1", "tag2"] } }, { "id": 2, "name": "Item 2", "details": { "description": "Second item description", "tags": ["tag3"] } } ] } } ``` I tried using `ConvertFrom-Json` to parse the response, but when I attempt to access the nested properties, I encounter an unexpected behavior. Here's my attempt at accessing the data: ```powershell $response = Invoke-RestMethod -Uri 'https://api.example.com/data' -Method GET $data = $response | ConvertFrom-Json foreach ($item in $data.data.items) { Write-Host "ID: $($item.id) - Name: $($item.name) - Description: $($item.details.description)" } ``` When I run this code, I get the following behavior: `want to bind argument to parameter 'description' because it is null.` It seems like the `details` property is not being parsed correctly, but I need to figure out why. I verified that the API is returning a valid JSON format and that I'm using the correct URL and method. I've also tried accessing the properties directly using `Select-Object`, but I still run into the same behavior when trying to access `details.description`. Am I missing something in how I parse the JSON or access these nested objects? Any insights would be greatly appreciated! I'm working on a service that needs to handle this. I'd really appreciate any guidance on this.
