Copying File to another sharepoint destination

从 DriveItem copy().post(...) 入口点以及 issue 中链接的 Microsoft Graph driveItem copy 文档开始。使用提供的 source、destination、ItemReference 和 CopyPostRequestBody 代码重现该场景，然后确定为什么没有应用替换，以及为什么 post() 返回 null。当所报告的复制行为和返回值已得到解释或纠正时，即视为完成。

Describe the bug

HI ,
I am copying a file from my sharepoint site to another location on the same site.
The first time i execute the code the file is copied correctly.
When i change the file content in the source folder and copy it again the code executes without errors but
the new file is not copied. In the destination folder there is still the file that was initialy copied.

I read the docs : https://learn.microsoft.com/en-us/graph/api/driveitem-copy?view=graph-rest-1.0&tabs=http
According to the docs i can use @microsoft.graph.conflictBehavior to replace the file in the destination but this does not work. The file is only copied once. When i delete the file in the destination the file is copied again.

This is the code i use.
Be sure that the referenced ids in the snipplet are fine and that in copyPostRequestBody the copyPostRequestBody.setParentReference(itemRefDestination); is set correctly.

DriveItem created = authenticationProvider.getGraphServiceClient().drives().byDriveId(driveRoot.getId()).items()
.byDriveItemId(driveItem.getId()).copy()
.post(copyPostRequestBody);

The other question i have here is: Why is "DriveItem created" always null ? According to the SDK post(...) returns a DriveItem. No matter if the copy is made (in the first place) or not the returned object is always null.

How can i make sure that changes made on the file in the source folder are always copied?

Expected behavior

I expect the file to be copied and the conflict behaviour provided is applied. As in when "replace" than its replaced , when "rename" the file is renamed in the destination.

How to reproduce

// get the source file as DriveItem 
DriveItem sourceItem= driveItemManager.getDriveItemByPath(source.getPath());

// get the destination location as DriveItem 
DriveItem destinationRoot = driveItemManager.getDriveItemByPath(destination.getPath());

// create ItemReference  from destination root.
 ItemReference itemRefDestination = new ItemReference();
    itemRefDestination.setDriveId(driveItemDest.getParentReference().getDriveId());
    itemRefDestination.setId(driveItemDest.getId());
    itemRefDestination.setName(destination.getName());

// create CopyPostRequestBody and set reference.
    CopyPostRequestBody copyPostRequestBody = new CopyPostRequestBody();
    copyPostRequestBody.setParentReference(itemRefDestination);

//execute the copy call -> myDriveId
DriveItem post = authenticationProvider.getGraphServiceClient().drives().byDriveId(myDriveId).items()
                        .byDriveItemId(sourceItem.getId()).copy()
                        .post(copyPostRequestBody);
