Hi,
I'm trying to download OneNote (.one) file inside the OneDrive using MS Graph API but always get 503 Service Unavailable Error.
I have tried 2 ways of downloading it.
First, using the URL available through the @microsoft.graph.downloadUrl property on the DriveItem.
GET /users/{userId}/drive/items/{item-id}
driveitem-get
Then, I tried to download the content using this endpoint
GET /users/{userId}/drive/items/{item-id}/content
driveitem-get-content
But the result is the same. It returns 503 Service Unavailable Error.
Here is the result if when download it from the browser using URL from @microsoft.graph.downloadUrl
Any idea what is the cause?
The file size is around 2.5 GB. Is the big OneNote size make it failed to download?
Thanks

@Edwin Fajar The GET /users/{userId}/drive/items/{item-id} retrieves the metadata of the drive item, not download it. Find details on this endpoint here
The GET /users/{userId}/drive/items/{item-id}/content request is suitable for driveItems with the file property according to the documentation of this API. One Note files have this property set to null.
You can get the content of a One Note as pages and sections instead. Kindly have a look at this MS Graph documentation on the endpoints you can utilize to do so.
@Fiona Matu Thanks for the reply. Yes, the GET /users/{userId}/drive/items/{item-id} is to retrieves the metadata of the drive item. And from the response body, there is @microsoft.graph.downloadUrl property that contains the download URL.
I have had a look at this MS Graph. I can get the content of a One Note as pages, but the content return in HTML format. For now, my priority is to download the One Note as .one file. I will try to consider the HTML format if there is no other way to download it as .one file.
Thanks

This still seems to be a problem with OneNote items around and above the size of 2GB. The download always fails with a 503.

I also have same issues. I can't download my one note file when its size has more than 2 GB. The error is exactly the same.
Can someone give the response to this as well?
