I'm retrieving the JSON representation of a SharePoint page using the endpoint:
GET https://graph.microsoft.com/v1.0/sites/${siteId}/pages/${pageId}/microsoft.graph.sitePage?expand=canvasLayout&select=id,name,webUrl,title,description,createdBy,canvasLayout,parentReference
I receive a JSON structure like this.

From the response, I parse out file metadata that’s attached to the page. For each file, I extract the following fields from data.properties:
uniqueId
listId
siteId
Then I attempt to retrieve detailed information about the file using the request:
GET https://graph.microsoft.com/v1.0/sites/${siteId}/lists/${listId}/items/${uniqueId}/driveItem?select=id,size,parentReference,name,webUrl,file,createdBy,folder
This request works for most files. However, for some files—despite having the correct uniqueId, listId, and siteId and even when I can manually verify that the file exists—the request returns a 404 error. I need the detailed JSON response mainly to obtain the webUrl to download the file.
My questions are:
Why might some files return a 404 even though their metadata appears correct?
What alternative approach (e.g., using a different endpoint) can I
use to reliably obtain the full JSON details for these file attachments?
Any insights or suggestions would be appreciated.
