Using SDK for delta fetching files from Sharepoint - get the versions for each file

Question

I'm using the delta functionality to monitor changes in Sharepoint- and need to get for each file it's versions - but for some reason it comes null -even if I use the select and send the "Versions" property

example:

graphClient
.drives(properties.getRootDriveId())
.root()
.delta()
.buildRequest()
.select("Versions,Name,WebDavUrl")
.get()

Hi @Bracha Steinberg ,

When we use the deltaLink URL for the first time, DriveItems that have been created and deleted prior to the initial delta query won't be returned that’s why we get null value (for example refer below screenshot).

After generating the delta token if there is any change occurred in the drive then it can be fetched using this delta token (for example refer below screenshot).

Also please note, you can fetch only latest modified version of a file with delta query.

Please refer the below documentation links for more information:
