4.0.0 appears broken at GoogleCloudLogging

[unaisvayani]

I have an application on .NET 5 using library Serilog.Sinks.GoogleCloudLogging Version="4.0.0" which is the latest version at this moment.

I have my custom logging library where Serilog is implemented to configure multiple sinks. While the logger object is being configured, I get this run time exception in the code below.

Here is the code where the sink is configured

 logger.WriteTo.GoogleCloudLogging(
      sinkOptions: config.options, 
      outputTemplate: config.OutputTemplate, 
      restrictedToMinimumLevel: config.minLevel);

Exception appears:

SysSystem.MissingMethodException
  HResult=0x80131513
  Message=Method not found: 'Void Google.Api.Gax.Grpc.ClientBuilderBase`1..ctor()'.
  Source=Google.Cloud.Logging.V2

Am I missing something to make it work?

Looks like the GCP team just released new libraries with breaking changes for GAX4 with a new underlying GRPC implementation.

https://github.com/googleapis/google-cloud-dotnet/releases/tag/Google.Cloud.Logging.V2-4.0.0

This library references Google.Cloud.Logging.V2 at version 3.6.0: https://github.com/manigandham/serilog-sinks-googlecloudlogging/blob/632c78de6fb47057611567865cfb9ad3b30adb17/src/Serilog.Sinks.GoogleCloudLogging/Serilog.Sinks.GoogleCloudLogging.csproj#L32

You can set it to that explicitly for now. I'll check on the upgrade issue later.

I referenced version 4.0.0 of Google.Cloud.Logging.V2 and it just worked. Thanks for the response @manigandham

Version 5.0.0 has been released that uses the new libraries. Support for netstandard2.0 has been dropped.
