BATCH update return error

[halflores]

When I run a batch update like the following.

I get the following error message:
{
"error" : {
"code" : "-1116",
"message" : "Could not commit transaction: Error -1 detected during transaction"
}
}
Thanks in advance

Hi, @halflores. I noticed that you are specifying "1" as the Content-ID for all your requests. This should be a unique identifier within your changeset.

If the problem still persists, see if you can share a small snippet of code that simulates the error so I can try to reproduce it on my end.

Hi,
Thank you. I would like to point out that there are times when the error message appears. So, is it possible that it is the memory allocated in SAP?
I am attaching the code

    public async Task<List<BatchResponse>> UpdateBatchItemsAsync(List<Item> itemEntidades, Login login)
    {
        try
        {
            List<SLBatchRequest> slBatchRequests = new List<SLBatchRequest>();
            List<BatchResponse> batchResponses = new List<BatchResponse>();
            int contentId = 1;
            foreach (Item itemEntidad in itemEntidades)
            {
                string source = string.Format("Items('{0}')", itemEntidad.ItemCode);
                SLBatchRequest slBatchRequest = new SLBatchRequest(HttpMethod.Patch, source, itemEntidad, contentId);
                slBatchRequests.Add(slBatchRequest);
                contentId +=1;
            }

            Tuple<HttpResponseMessage[], string> results = await _slConnections[login.SLConexion].PostBatchAsync(slBatchRequests.ToArray<SLBatchRequest>());

            batchResponses = SAPFunctions.MapResponse(results);
            
            return batchResponses;
        }
        catch (Exception ex)
        {
            _logger.LogError(ex, "UpdateBatchItemsAsync");
            throw;
        }
    }

Thank you.
