Method not found exception

[V Kuznetsov]

Hi,

Simple call to get a service throws me this error:

System.MissingMethodException: Method not found: 'Grpc.Core.CallInvoker Grpc.Core.Interceptors.ChannelExtensions.Intercept(Grpc.Core.Channel, Grpc.Core.Interceptors.Interceptor)'.    
at Google.Ads.GoogleAds.Lib.GoogleAdsServiceClientFactory.GetService[TService,TServiceSetting](ServiceTemplate`2 serviceTemplate, GoogleAdsConfig config)    
at Google.Ads.GoogleAds.Lib.GoogleAdsClient.GetService[TService,TServiceSetting](ServiceTemplate`2 serviceTemplate)

This is the line that causes it:

CustomerServiceClient customerService = client.GetService(global::Google.Ads.GoogleAds.Services.V3.CustomerService);

My relevant packages:

 <PackageReference Include="Google.Ads.GoogleAds" Version="2.8.0" />
 <PackageReference Include="Google.Apis.Auth.Mvc" Version="1.44.1" />
 <PackageReference Include="Google.Apis.Oauth2.v2" Version="1.44.1.1869" />
 <PackageReference Include="Google.Apis.ShoppingContent.v2_1" Version="1.44.1.1882" />

It's a class library, used in a web api project.

 <TargetFrameworks>net472;netcoreapp2.2</TargetFrameworks>

Please help to resolve the error. 

Thank you.

Hi,

The issue you are facing is Content API related. You will need to reach out to their team via their forum.

Please explain how is this Content API related. I explicitly call Google Ads methods.

Hello,

I initially thought this was Content API related because of the package you mentioned below

 <PackageReference Include="Google.Apis.ShoppingContent.v2_1" Version="1.44.1.1882" />

Are you using our client libraries? Do you have any logs associated with these calls or only the errors being thrown?

Thanks,

[V Kuznetsov]

Hi Anthony, 

I installed the nugets listed in the original post. In the logs I see only the error I posted above.

Hi,

I'll need to see if this something related to the actual API or the way you have it set up. Can you please reply privately to author your code and any files that contain the dependencies?
