[StanlyLife]

Description

I am trying to BulkInsert a lot of rows in a table on a schedule.
Whenever hangfire first executes the function, everything runs smoothly. However second time I try to bulkinsert, i get this error:

System.IndexOutOfRangeException: 'There is no row at position 0.'

Code

        public void AddRange(List<CardVehiclesUsedPo> cvu)
        {
            db.BulkInsert(
                cvu,
                options =>
                {
                    options.InsertIfNotExists = true;
                    options.AllowDuplicateKeys = true;
                    options.ColumnPrimaryKeyExpression = p =>
                        new
                        {
                            p.DriverCardId,
                            p.VehicleOdometerBegin,
                            p.VehicleRegistrationNumber
                        };
                }
            );
            db.SaveChanges();
        }

I’m out of the office. But is it possible to share the code & database privately?

Upon further investigation I found that this problem only happened to certain json files and data, but there is no clear indication on what’s causing the error as the models are the same.

Hello @StanlyLife ,

You can send your project here: info@zzzprojects.com (or talk more privately to us at this mailbox).

In this case, we will surely wait for your project, which will make it easier for us to reproduce it.

Best Regards,

Jon
