Empty default libraries - error 404

Problem

All document libraries in KONNEKT and mapped drives are empty.

Background

There are glitches in certain data centers hosting SharePoint Online on Microsoft's site. KONNEKT uses Microsoft's GraphAPI to access all information related to document libraries and their content.

Especially the request to get the default document library from a Site Collection (Get drive). KONNEKT's logs should contain entries if the default library operations fail:

To investigate, use GraphExplorer to check the get request for this document library:

Workarounds

1) Enable the setting "Add all SharePoint document libraries".

If enabled KONNEKT will use the List drives request to retrieve all document libraries from Site Collections.

Please be aware that enabling this setting will cause existing file links to break.

2) Use "Managed Mappings" to map the important document libraries and disable the setting "Sharepoint Sites Autodiscovery".
