Download and read a JSON file from OneDrive.

Uploads a small JSON document, downloads it via get_content(), parses it back with json.loads, and prints the contents.

A .json file is served by the OneDrive /content endpoint with Content-Type: application/json, so without the raw-content handling this used to fail (the client tried to parse the file as an OData response).

Permissions

Requires delegated permission Files.ReadWrite.
