unauthorized access with beta 1

[OneCyrus]

I can't get this to work with the new InfluxDB v2.0 beta 1. i always get a "unauthorized access" exception. i tried to run influx db beta 1 on multiple systems and with different access tokens. the error was always the same.

The batch item wasn't processed successfully because: InfluxDB.Client.Core.Exceptions.HttpException: unauthorized access
   at InfluxDB.Client.WriteApi.<>c__DisplayClass5_2.<.ctor>b__18(Exception e) in C:\source\influxdb-client-csharp\Client\WriteApi.cs:line 124
   at System.Reactive.Linq.ObservableImpl.SelectMany`2.ObservableSelector._.OnNext(TSource value) in D:\a\1\s\Rx.NET\Source\src\System.Reactive\Linq\Observable\SelectMany.cs:line 865

are there some compatibility changes in beta 1? with the alphas it worked fine.

on influxdb itself i see the following in the log:

Hi @OneCyrus,

The client doesn't have compatibility requirements between alpha and beta.

I added build over beta - https://circleci.com/gh/influxdata/influxdb-client-csharp/239 and tests passed.

Please, try validate token via:

curl -i -X POST 'http://localhost:9999/api/v2/write?org=my-org&bucket=my-bucket' \
    -H 'Authorization: Token my-token' \
    -d 'h2o,location=west level=1'

Regards

[OneCyrus]

with curl it works. so either there is something strange in my code (which used to work with the alpha) or I'm hitting an edge case with the lib.

[bednar]

You could enable tracing HTTP header information via LogLevel:

Client.SetLogLevel(LogLevel.Headers);

and check if a token is correct.

[OneCyrus]

it looks like the client omits the set token:

[OneCyrus]

my breakpoint doesn't hit here:

influxdb-client-csharp/Client/Internal/ApiClient.cs

Line 58 in dea0c9d

if (InfluxDBClientOptions.AuthenticationScheme.Token.Equals(_options.AuthScheme))

so it doesn't inject the authentication token.

[OneCyrus]

ok _signout is true and so leaves the function early

[bednar]

It's caused by calling InfluxDBClient.Dispose().

You should call Dispose on Client as a last statement.

[OneCyrus]

i don't dispose it myself. the issue is that InfluxDB hadn't authentication on the writeAPI until recently. so it breaks now. looks like this never worked in the client itself. older releases have the same issue.

[OneCyrus]

it looks like there are also some concurrency issues. when using() (which auto disposes) is used the client usually signs out before the queue is processed.

[bednar]

I think it's a combination of recent changes in InfluxDB 2 and how is disposed WriteApi.

Currently I am working on fix in branch fix/dispose-race-condition.
