Hitting 30 minute credential timeout

[jaaydub42]

I have a large Sharepoint upload that is taking over 30 minutes, and the access credential is expiring.

I am handling the upload in chucks using the start_upload, continue_upload, and finish_upload functions. That part appears to be working fine. But before completion I am hitting a token timeout.

It appears that in the adal library there is a acquire_token_with_refresh_token function, but I am not seeing this implemented.

Is there a method of refreshing my client credential token using your library that I am missing?

Hi, I'm getting the same issue trying to upload a large file (~4GB, with 10Mb upload speed) using the example for Sharepoint large files (https://github.com/vgrem/Office365-REST-Python-Client/blob/master/examples/sharepoint/files/upload_large_file.py). After 30 minutes, download is stopped and I get a 403 response with "The security validation for this page has timed out". Is there any way to circumvent this limitation until the token refresh is implemented? How can I upload a file that big currently. I'm using SAML authentication. Thank you.

Staring from 2.3.9 version SharePoint client introduces support to determine if security validation is expired. If it gets expired, it refresh it automatically to prevent the exception: The security validation for this page has timed out to occur.
