Hi Chen, Nyon-ZL,

Thanks for reaching out to Microsoft!

400 error occurs when the request can't be processed because it's malformed or incorrect.

Graph API to upload files to SharePoint drive:

PUT /sites/{site-id}/drive/items/{parent-id}:/{filename}:/content 

If you want to upload large files, you can upload large files with an upload session, please try to use the following Graph API to create an upload session:

POST /sites/{siteId}/drive/items/{itemId}/createUploadSession 

Upload small files: Upload or replace the contents of a DriveItem (Note: This method only supports files up to 4MB in size.)

Upload large files: Upload large files with an upload session

Ensure that the Graph API is valid to upload files.

Hope this helps.
