http://localhost:8086/api/v2/query?org={org} method not allowed

[shaktee]

Describe the bug

I am using the queryService.query() to make a query and it is returning a 400 (Bad Request) with the following

{
"code": "method not allowed",
"message": "allow: OPTIONS, POST"
}

To Reproduce
Steps to reproduce the behavior:

1. Run an influxdb database InfluxDB v2.7.10 (git: f302d9730c) build_date: 2024-08-16T20:19:28Z
2. Perform a query

 var client = InfluxDBClient(
        url: 'http://localhost:8086',
        token: '<token>',
        org: 'ORG',
        bucket: 'BUCKET',
        client: RemoveUserAgentClient(),
        debug: true);

var queryService = client.getQueryService();
var records = await queryService.queryRaw(''' ... ''');

Expected behavior
Expect a string of records in records

Specifications:

• Client Version: influxdb_client: ^2.10.0
• InfluxDB Version: InfluxDB v2.7.10 (git: f302d9730c) build_date: 2024-08-16T20:19:28Z
• Platform: GCP instance Linux 6.1.0-23-cloud-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.99-1 (2024-07-15) x86_64 GNU/Linux

Additional context
I had to strip the user agent info because chrome was erroring out with unsafe header errors if I did not do that. the code for that is

class RemoveUserAgentClient extends http.BaseClient {
  final http.Client _inner = http.Client();

  RemoveUserAgentClient();

  @override
  Future<http.StreamedResponse> send(http.BaseRequest request) {
    request.headers
        .removeWhere((key, value) => key.toLowerCase() == 'user-agent');
    return _inner.send(request);
  }
}
