Export to PDF not working

Question

I modified your sample Blazor Bar Chart Example - Syncfusion Demos adding some lines to export the chart in pdf as in the attachment but when I select this option, I receive a page with "attempting to reconnect 1 of 8" and after a while I can use again the page but without any export to pdf file. The same code works in Blazor server version 18. Now I'm using version 19.1.0.66

Hi Walter, 
  
Based on the console error reported, we suspect that the reported scenario occurs due to the less buffer size. Hence we suggest you to use 100MB or more over the SignalR connection in startup.cs page in your project to overcome the reported scenario. Please find the code snippet below for further reference. 
  
Code Snippet: 




Startup.cs: 
  
using Syncfusion.Blazor; 
namespace BlazorApplication 
{ 
public class Startup 
{ 
    .... 
    .... 
    public void ConfigureServices(IServiceCollection services) 
    { 
        .... 
        .... 
        services.AddSyncfusionBlazor(); 
        services.AddSignalR(e => { 
          e.MaximumReceiveMessageSize = 1024000; 
        }); 
    } 
} 
}
