Hi @MichaelHan-MSFT,
I am trying to upload a large excel file using the createuploadsession option in Graph API via Postman. Below are the settings that I selected:

I get the success message but no Upload URL is returned. May I know if I am missing something or any details are incorrect? Also can you tell where I should specify the drive file name(source file) and the Sharepoint filename(destination file)?
