InfluxDB Client 6.8.0 with createV1 uses POST /api/v2/write instead of POST /write

[polarnik]

Steps to reproduce:
List the minimal actions needed to reproduce the behavior.

1. Install InfluxDB v2
2. Create a bucket 28c2cbcbac4cf29f
3. Create v1 auth token with a name UserName and password: Password

influx v1 auth create \
--read-bucket 28c2cbcbac4cf29f --write-bucket 28c2cbcbac4cf29f \
--username UserName

5. Create v1 database with name DataBase and retention policy auto

influx v1 dbrp create \
--bucket-id 28c2cbcbac4cf29f --db DataBase --rp auto

7. Try to write some metrics via V1 endpoint:

        try (InfluxDBClient client = InfluxDBClientFactory.createV1(
               "http://127.0.0.1:8086",
               "UserName",
               "Password".toCharArray(),
                "DataBase",
               "auto"
        )) {
            try (WriteApi writeApi = client.makeWriteApi()) {
                writeApi.writePoint(point);
                writeApi.flush();
            }
        }

Expected behavior:
HTTP request via
https://docs.influxdata.com/influxdb/v2.7/reference/api/influxdb-1x/write/
HTTP request:

POST /write?db=DataBase&rp=auto HTTP/1.1

Actual behavior:

It doesn't work. Only 401 Errors.

Specifications:

• Client Version: 6.8.0
• InfluxDB Version: 2.6.1
• JDK Version: 17
• Platform: MacOS

Workaround:
Use
https://github.com/influxdata/influxdb-java
instead of
https://github.com/influxdata/influxdb-client-java
for working with v1

Workaround with org.influxdb:influxdb-java:2.23

//Point from https://github.com/influxdata/influxdb-client-java
import com.influxdb.client.write.Point; 

// Client from https://github.com/influxdata/influxdb-java
import org.influxdb.InfluxDB;
import org.influxdb.InfluxDBFactory;

...

        final InfluxDB influxDB = InfluxDBFactory.connect(InfluxDBAddress, Username, Password);
        influxDB.setDatabase(DataBase);
        influxDB.setRetentionPolicy(RetentionPolicy);
        InfluxLineGenerator influxLineGenerator = new InfluxLineGenerator(); // Some generator
        ArrayList<Point> points = influxLineGenerator.getPointList();
        for(Point point: points) {
            influxDB.write(DataBase, RetentionPolicy, InfluxDB.ConsistencyLevel.ALL, TimeUnit.MILLISECONDS,
                    point.toLineProtocol());
        }
        influxDB.close();

Gradle config:

    implementation("org.influxdb:influxdb-java:2.23")
    implementation("com.influxdb:influxdb-client-java:6.8.0")

Some important case:

1. Send a point with tags and values
2. Send a point with the same tags and values but with a new time

InfluxDB 1.8 POST /write - we will see the 2nd point in the DB
InfluxDB 2.6.1 POST /write - we will see the all points in the DB
