title: ArgumentException: The 'ClientId' option must be provided. (Parameter 'ClientId')
body: <p>I am using google authentication in core 3.1. Previously, my code was working fine but after having system format the project is giving me an exception.
  *<strong>ArgumentException: The 'ClientId' option must be provided. (Parameter 'ClientId')
  Microsoft.AspNetCore.Authentication.OAuth.OAuthOptions.Validate()</strong></p>
  <p>I have given the Client ID in startup which is like this:</p>
  <pre><code>services.AddAuthentication()
  .AddGoogle(options =&gt;
  {
      IConfigurationSection googleAuthNSection =
          Configuration.GetSection(&quot;Authentication:Google&quot;);
      options.ClientId = googleAuthNSection[&quot;7111841*********&quot;];
      options.ClientSecret = googleAuthNSection[&quot;uc**************&quot;];
  });
  </code></pre>
  <p>Please help me with this</p>
