Cannot get conflict behaviour to work with upload to sharePoint

Hi. I am trying to get the various settings of fail/replace/rename to work, in both C# code and when this has failed in Postman. I am using it in an upload session. The URL is https://graph.microsoft.com/v1.0/sites/mysite/drives/driveidhere/root:/testfile.txt:/createUploadSession/drives/driveidhere/root:/testfile.txt:/createUploadSession

 

The JSON body is 

{
  "@microsoft.graph.conflictBehavior": "rename"
}
 
This generates a session URL and within my C# code then goes on to upload perfectly. But it always does a replace. Looking at the upload URL is shows the conflict behaviour which is always:
nameConflictBehavior=Replace
So Pernille-Eskebo.graph.conflictBehavior is not being recognised. I've tried rename and fail.
Any ideas?
 
Thanks
 
Paul

    Paul_Red1 as states the documentation at https://docs.microsoft.com/en-us/graph/api/resources/driveitem?view=graph-rest-1.0

     

    Notes: The parameter @microsoft.graph.conflictBehavior should be included in the URL instead of the body of the request.

     

    So try to include it in the URL not in the body.

    Just to say I have this working - the documentation is appalling!

     

    The page https://docs.microsoft.com/en-us/graph/api/driveitem-createuploadsession?view=graph-rest-1.0

     

    does not show that in the request the conflict behaviour setting should be wrapped in an "item" object. Please can we have some more examples in the documentation.

     

    Thanks

      Hi All, I am also facing the same issue in my code. While creating uploadsession, unable to get proper session created.

      Even though the properties set to

      "@microsoft.graph.conflictBehavior": "fail",

      Its overwriting the files.

      Could any one please help. I am using golang and Code is
      http.newRequest(POST, URL, Body)
      Body = {
      "@microsoft.graph.conflictBehavior": conflictOption,
      "description": "",
      "name": filePath,
      "item": map[string]string{"@microsoft.graph.conflictBehavior": conflictOption},
      "deferCommit": true}

      Also I have tried all possible combinations for setting up properties. graph api always sending response which is overwriting the file in onedrive.
