The format of value xxx is invalid

I get the following exception when I run the code (I use Mac):

The format of value ‘Darwin17.7.0DarwinKernelVersion17.7.0WedOct10230614PDT2018rootxnu-4570.71.131/RELEASE_X86_64’ is invalid.

Code that throws an exception

var serviceClientCredentials = new AzureApiKeyServiceClientCredentials("<key>");
// Throw an exception here
var client = new TextAnalyticsClient(_serviceClientCredentials);

ServiceClientCredentials class:
 
    public class AzureApiKeyServiceClientCredentials : ServiceClientCredentials
    {
        private readonly string _subscriptionKey;

        public AzureApiKeyServiceClientCredentials(string subscriptionKey)
        {
            _subscriptionKey = subscriptionKey;
        }
        
        public override Task ProcessHttpRequestAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            request.Headers.Add("Ocp-Apim-Subscription-Key", _subscriptionKey);
            
            return base.ProcessHttpRequestAsync(request, cancellationToken);
        }
    }

Update 1 I think TextAnalyticsClient tries to set a header key/value and header value is not valid.

Update 2 I see the source of the problem. Its setting OsVersion on header of HttpClient and it’s not url friendly or something and HttpClient is throwing an exception:

 this.UpdateDefaultUserAgentList("OSVersion", this.OsVersion);

So all you need to do it to fix it is to always call CleanUserAgentInfoEntry(_osVersion).

@amir734jj @bastisk can you tell me what version of ClientRuntime are you using in your app? If you upgrade your app to the latest ClientRuntime, you should not see this issue. https://www.nuget.org/packages/Microsoft.Rest.ClientRuntime/2.3.18

I got the same issue working with Microsoft.Azure.Batch on MacOS Mojave and crashed on the same scenario:

BatchClient batchClient = BatchClient.Open(batchCredentials)

Adding latest Microsoft.Rest.ClientRuntime also fixed the issue for me.
