Onedrive-api-docs: `@microsoft.graph.conflictBehavior` in driveitem copy

Expected or Desired Behavior

Copying a driveitem allows for defining @microsoft.graph.conflictBehavior to handle conflicts, as per design according to issue #759

This should also be documented.

Observed Behavior

Conflicts cause 409 Conflict response despite @microsoft.graph.conflictBehavior.

{
  "error": {
    "code": "nameAlreadyExists",
    "message": "The specified item name already exists.",
    "innerError": {
      "request-id": "{requestId}",
      "date": "{date}"
    }
  }
}

Steps to Reproduce

POST https://graph.microsoft.com/v1.0/users/{username}/drive/items/{itemId}/copy

{
  "parentReference": {
    "driveId": "{driveId}",
    "id": "{parentItemId}"
  },
  "name": "foo",
  "@microsoft.graph.conflictBehavior": "rename"
}

^ Making this request twice will cause 409 Conflict nameAlreadyExists on the second try.

I'm trying this aswell using the Graph API and it always returns nameAlreadyExists regardless of the behaviorConflict specified

{
  "parentReference": {
    "driveId": "{driveId}",
    "id": "{parentItemId}"
  },
  "name": "test",
  "@microsoft.graph.conflictBehavior": "rename"
}

How to work around this ??

I can also confirm that this still does not function properly.

Adding @microsoft.graph.conflictBehavior=rename to query string parameters did work for me

[jl0zano]

as @marcogiannetta said, you have to add to the query params.

Example:
https://graph.microsoft.com/v1.0/me/drive/items/{your-file-id}/[email protected]=rename

If you're using the C# Graph SDK you have to send a query option on the request.

List<QueryOption> options = new List<QueryOption>
{
    new QueryOption("@microsoft.graph.conflictBehavior", "rename")
};

Well docs should be updated then

It looks like the workaround above only works for OneDrive for Business... OneDrive Personal still seems to ignore it.

Adding @microsoft.graph.conflictBehavior to query string doesn't work either:

https://graph.microsoft.com/v1.0/me/drive/items/{your-file-id}/[email protected]=replace

Edit: It actually works, my bad. I just had different unrelated error (overwrite is not supported for folders)
