No response on BatchHandler with multiples requests

[WSMaxx]

Dear all,

Hope you are fine.

We have an issue with BatchHandler when we try to send multiples requests in TrippinMemory Web api like.

We have this service in WebConfig:

                ODataBatchHandler myappsBatchHandler = new MyAppsBatchHandler(GlobalConfiguration.DefaultServer);
                myappsBatchHandler.ODataRouteName = routeName;
                services.AddSingleton(myappsBatchHandler);

BatchHandler is the same as trippin memory sample.

If we update one value in the batch, no problem (operation != null), but when we would like update multiple values (changeset != null) , we have no response, batch is pending.

Instead, data are always updated in the database with EF6.

We put the lastet update, but no change.

This payload work:

--batch_id-1622205634979-23
Content-Type:application/http
Content-Transfer-Encoding:binary

PATCH user_list(16) HTTP/1.1
Accept:application/json;odata.metadata=minimal;IEEE754Compatible=true
Accept-Language:fr-FR
Content-Type:application/json;charset=UTF-8;IEEE754Compatible=true

{"active":false}
--batch_id-1622205634979-23--
Group ID (API): user_listGroup

This does not send response:

--batch_id-1622200586786-21
Content-Type: multipart/mixed;boundary=changeset_id-1622200586786-22

Hope you can help us to solve this issue.
