Create operation processor does not support DataList of Operation.

[voronizer]

Sending data:

{
  "operations": [{
    "op": "add",
    "data": [{
      "type": "mytype",
      "attributes": {
        "time": "2019-02-20T09:08:37",
        "type": 1
      }
    }]
  }]
}

It fails with:

[12:29:02 Error] JsonApiDotNetCore.Middleware.JsonApiExceptionFilter
An unhandled exception occurred during the request
JsonApiDotNetCore.Internal.JsonApiException: Transaction failed on operation[0] (add). ---> JsonApiDotNetCore.Internal.JsonApiException: Failed to deserialize document as json:api.

Here is only DataObject processed. But not DataList.

JsonApiDotNetCore/src/JsonApiDotNetCore/Services/Operations/Processors/CreateOpProcessor.cs

Lines 51 to 54 in ec5fa84

	public async Task<Operation> ProcessAsync(Operation operation)
	{
	var model = (T)_deSerializer.DocumentToObject(operation.DataObject);
	var result = await _service.CreateAsync(model);

I'm closing this, because atomic operations does not allow to send multiple resources in a single add operation. When adding multiple resources, put them in separate operations within a single request.
