416 Error when initiating upload
I'm trying to initiate an upload by posting to:
/d2l/api/lp/(version)/(orgUnitId)/managefiles/file/upload
I'm including the required headers (with the actual token where the placeholder is):
{ 'Authorization': 'Bearer <TOKEN>', 'X-Upload-Content-Type': 'text/csv', 'X-Upload-Content-Length': '530', 'X-Upload-File-Name': 'upload_test.csv'}
However, I'm getting the following error: 416 Requested Range Not Satisfiable
And response.text reads:
{"detail":"The page cannot be displayed because the request range was not satisfiable."}
I can find no information about this error on the community (or anywhere else online). Does anyone have insight?

Is there any chance you would be able to share your Python script or function calls? I am working on something very similar (uploading a file to a dropbox as feedback) and have been getting some related errors. That would be a huge help!

I’m unable to provide the Python script, but since there hasn’t been a response yet, I wanted to close the loop for anyone encountering this issue in the future. If you see the error:
{"detail":"The page cannot be displayed because the request range was not satisfiable."}
in Postman, when initiating an upload, the likely cause is redirect-follow behavior. Postman automatically follows the 308 Resume Incomplete response as a redirect, which leads to an invalid range request.
Fix:- Disable “Follow redirects” for this request (go to the request → Settings tab).
- Send the request again and inspect the first response, specifically:
- Status Code (should be
308 Resume Incomplete) - Location header
- Status Code (should be
