Influx 1.8 OSS with 2.0.0 client: InfluxDBException: statusCode = 401, code = null, message = null

[BSBoatia]

Describe the bug
Authentication fails, when trying to query a 1.8.5 based Influx instance with the 2.0.0 flutter client.

[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: InfluxDBException: statusCode = 401, code = null, message = null #0 DefaultService._handleResponse package:influxdb_client/client/influxdb_client.dart:108 <asynchronous suspension> #1 QueryService._send package:influxdb_client/client/query_service.dart:80 <asynchronous suspension> #2 QueryService.query package:influxdb_client/client/query_service.dart:66 <asynchronous suspension> #3 _SysHealthState._loadHistoricalData package:screens/syshealth.dart:222 <asynchronous suspension>

To Reproduce
Steps to reproduce the behavior:

1. Query data from a 1.8.5 influx db with auth-enabled = true

Expected behavior
The query to execute successfully as it does with influxdb_client: ^1.1.0

Specifications:

• Client Version: influxdb_client: ^2.0.0
• InfluxDB Version: 1.8.5
• Platform: Flutter (running client on iOS)

Additional context
The code is working fine with influxdb_client: ^1.1.0

Sample code I used works with client 1.1.0 but not 2.0.0

InfluxDBClient client = InfluxDBClient(
        url: 'http://localhost:8086',
        username: 'my_user',
        password: 'my_password',
        org: '',
        bucket: 'my_db',
        debug: false);

    QueryService queryService = client.getQueryService();

    String fluxQuery = '''
    lat = from(bucket: "my_db")
          |> range(start: -1d)
          |> filter(fn: (r) => r["_measurement"] == "gps_pos")
          |> filter(fn: (r) => r["_field"] == "lat")
          |> limit(n:20)

    long = from(bucket: "my_db")
          |> range(start: -1d)
          |> filter(fn: (r) => r["_measurement"] == "gps_pos")
          |> filter(fn: (r) => r["_field"] == "long")
          |> limit(n:20)

      join(tables: {lat: lat, long: long}, on: ["_time"])
    ''';

    Stream<FluxRecord> recordStream = await queryService.query(fluxQuery);
    await recordStream.forEach((record) {
      double lat = double.parse(record["_value_lat"].toString());
      double long = double.parse(record["_value_long"].toString());
      print('${record["_time"]} lat: $lat long: $long');
    });

Hi @BSBoatia,

thanks for using our client.

I have prepared a fixed version within #26.

If you would like to use the fixed version of the client before release into pub.dev, then you can import the library by:

dependencies:
  influxdb_client:
    git:
      url: [e-mail]:influxdata/influxdb-client-dart.git
      ref: fix/authorization-v1

• https://dart.dev/tools/pub/dependencies#git-packages

Regards

@bednar works great. Thanks a lot for fixing it!
