DAV HTTPResponseError 500 when send files bigger than 10MB

[Brawn1]

If we send files bigger then 10 MB, the Client split the files in chunks and add this in header.
The Webdav from Owncloud response this with an DAV 500 Error.

To Reproduce this:

• Python3.9
• Owncloud 10.14.0
• file bigger as 10MB

import owncloud

oc = owncloud.Client.from_public_link('https://cloud.example.com/s/JABC123', folder_password='secret', debug=True)

print('start upload 12m_test.img')

oc.upload_file(remote_path='/12m_test.img',  local_source_file='12m_test.img') 

print('Done')

start upload 12m_test.img
DAV request: PUT /12m_test.img-chunking-1712240400-2-0
Headers:  {'X-OC-MTIME': '1712240000', 'OC-CHUNKED': '1'}
DAV status: 500

owncloud.owncloud.HTTPResponseError: HTTP error: 500

When i set chunked=False, then the Upload works.
I have tested this up to 50MB, with no Problem.

So i think, this is an issue with the DAV Chunked Protocol in the new Owncloud Version.
