  hi

  1.

  Please share the code of HQSOFT.eBiz.CoreBackend.AuditLogging.ExtendedAuditLogContributor class. there is a NullReferenceException

  2.

  Please set log level to Debug and re-share the logs.

  public class Program
  {
      public async static Task<int> Main(string[] args)
      {
          Log.Logger = new LoggerConfiguration()
              .MinimumLevel.Debug()
              .MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Warning)
              .Enrich.FromLogContext()
              .WriteTo.Async(c => c.File("Logs/logs.txt"))
              .WriteTo.Async(c => c.Console())
              .CreateLogger();
  

  Thanks.

  Here are of AuditLogContributor (I have fixed issue of NullReferenceException) and new log file:

  public class ExtendedAuditLogContributor : AuditLogContributor
  	{
  		public override void PreContribute(AuditLogContributionContext context)
  		{
  			var urlProp = context.AuditInfo.GetProperty("ScreenUrl");
  			var url = context.GetHttpContext().Request.Headers["screen-url"].ToString();
  			if (urlProp != null && string.IsNullOrEmpty(url))
  				context.AuditInfo.SetProperty("ScreenUrl", url);
  		}
  
  		public override void PostContribute(AuditLogContributionContext context)
  		{
  			var currentUser = context.ServiceProvider.GetRequiredService<ICurrentUser>();
  
  			foreach (var change in context.AuditInfo.EntityChanges)
  			{
  				var screenUrl = context.GetHttpContext().Request.Headers["screen-url"].ToString();
  				if (string.IsNullOrEmpty(screenUrl))
  					continue;
  				var uri = new Uri(screenUrl);
  				var path = uri.PathAndQuery;
  				var lastIndex = path.LastIndexOf('/');
  
  				var urlDoc = path.Substring(0, lastIndex + 1);
  				var docId = path.Substring(lastIndex + 1);
  
  				change.SetProperty("ScreenUrl", urlDoc);
  				change.SetProperty("DocId", docId);
  
  				change.SetProperty("UserId", currentUser.Id);
  			}
  		}
  	}

  hi

  Your PreContribute has a problem please debug your app to see which variable is null

  [WRN] Object reference not set to an instance of an object.
  System.NullReferenceException: Object reference not set to an instance of an object.
     at HQSOFT.eBiz.CoreBackend.AuditLogging.ExtendedAuditLogContributor.PreContribute(AuditLogContributionContext context)
     at Volo.Abp.Auditing.AuditingHelper.ExecutePreContributors(AuditLogInfo auditLogInfo)
  

  public override void PreContribute(AuditLogContributionContext context)
  {
      var urlProp = context.AuditInfo.GetProperty("ScreenUrl");
      var url = context.GetHttpContext().Request.Headers["screen-url"].ToString();
      if (urlProp != null && string.IsNullOrEmpty(url))
      context.AuditInfo.SetProperty("ScreenUrl", url);
  }

  hi

  Do you have the configuration below in your Blazor client project?

  https://abp.io/docs/latest/modules/chat#blazor-webassembly-ui

  
  Configure<ChatBlazorWebAssemblyOptions>(options =>
  {
      options.SignalrUrl = builder.Configuration["RemoteServices:Chat:BaseUrl"];
  });
