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

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

InfluxDBClientFactory.createV1 から始め、makeWriteApi と AbstractWriteClient までリクエストパスを追跡します。生成されたリクエストをドキュメント化されている InfluxDB 1.x の /write エンドポイントと比較し、InfluxDB 2.6.1 に対する再現手順を使って修正を検証します。期待されるパスと認証動作も確認してください。
