Problems loading reference while authoring resource manifest

Prerequisites

Summary

I am experiencing issues while authoring a resource manifest. Whenever defining the URL shortener: https://aka.ms/dsc/schemas/v3/bundled/resource/manifest.json, the manifest.export.json file cannot be loaded.

Changing this to: https://raw.githubusercontent.com/PowerShell/DSC/main/schemas/v3/bundled/resource/manifest.json helps me with the IntelliSense features in VSCode.

Steps to reproduce

1. Create a test.dsc.resource.json file
2. Add "$schema": "https://aka.ms/dsc/schemas/v3/bundled/resource/manifest.json"

The warning appears.

Expected behavior

All file references are loaded.

Actual behavior

Not all file references are loaded, breaking some IntelliSense features.

No response

Reproduce the warning with test.dsc.resource.json using the aka.ms schema URL, then compare its loading with the raw GitHub URL and inspect the referenced manifest.json and manifest.export.json. Done means all file references load and the affected VS Code IntelliSense features work without the warning.
