WriteRecordsAsync ignores first one

[rferreiraperez]

Steps to reproduce:

I would like to write asyncronously a set of records using Line Protocol format.

I'm working with a following dataset:

measurement1,tag1="value1",tag2="value2" field1=110,field2=120,field3=130,field4=140 1673028005 measurement1,tag1="value1",tag2="value2" field1=210,field2=220,field3=230,field4=240 1673028010 measurement1,tag1="value1",tag2="value2" field1=410,field2=420,field3=430,field4=440 1673028015 measurement1,tag1="value1",tag2="value2" field1=610,field2=620,field3=630,field4=640 1673028020 measurement1,tag1="value1",tag2="value2" field1=810,field2=820,field3=830,field4=840 1673028025 measurement1,tag1="value1",tag2="value2" field1=1010,field2=1020,field3=1030,field4=1040 1673028030 measurement1,tag1="value1",tag2="value2" field1=1210,field2=1220,field3=1230,field4=1240 1673028035 measurement1,tag1="value1",tag2="value2" field1=1410,field2=1420,field3=1430,field4=1440 1673028040 measurement1,tag1="value1",tag2="value2" field1=1610,field2=1620,field3=1630,field4=1640 1673028045 measurement1,tag1="value1",tag2="value2" field1=1810,field2=1820,field3=1830,field4=1840 1673028050 measurement1,tag1="value1",tag2="value2" field1=2010,field2=2020,field3=2030,field4=2040 1673028055 measurement1,tag1="value1",tag2="value2" field1=2210,field2=2220,field3=2230,field4=2240 1673028060 measurement1,tag1="value1",tag2="value2" field1=2410,field2=2420,field3=2430,field4=2440 1673028065

And my code is:

        IEnumerable<string[]> batches = CreateBatches(data);
        using InfluxDBClient influxDBClient = new(Options.Host, Options.Token);
        WriteApiAsync writeApiAsync = influxDBClient.GetWriteApiAsync();
        foreach (var records in batches)
        {
            await writeApiAsync.WriteRecordsAsync(records, WritePrecision.S, Options.Bucket, Options.Organization, cancellationToken);
        }

Expected behavior: I expected all the records to be written but it always ignore the first one.

Actual behavior: All points except the first one are written.
