Issue in fiskaltrust.Middleware.Interface.Client.Grpc

Closed this issue · 1 comments

It seems like the dependencies must ne updated in this library.
Compiling a release APK which is using your fiskaltrust.Middleware.Interface.Client.Grpc nuget package is causing issues in production :

System.TypeInitializationException: The type initializer for 'DefaultProxyCache`3' threw an exception. ---> System.ArgumentException: Get Method not found for 'Name'

After we updated all referenced libs to their latest version the issue disappeared.

Together with the issue we discovered another issue, probably related to your reply logic

IPOS client is intialized like this

var retryOptionsGrpc = new RetryPolicyOptions { ClientTimeout = TimeSpan.FromSeconds(2), DelayBetweenRetries = TimeSpan.FromSeconds(1), Retries = 2 };
return GrpcPosFactory.CreatePosAsync(new GrpcClientOptions { Url = new Uri(cashBoxConfiguration.Url), RetryPolicyOptions = retryOptionsGrpc }).Result;

And this is causing this :

System.TypeInitializationException: The type initializer for 'DefaultProxyCache`3' threw an exception. ---> System.ArgumentException: Get Method not found for 'Name'
