Reload with query parameters Sitecore Forms custom submit action

Question

I Have Created custom submit action in sitecore 9 forms.

In that custom action, I want to reload a same the page with adding of query parameters.

So far I tried.

 Log.Error(Error, typeof(SendDataToApi));
 Log.Error(ErrorDescription, typeof(SendDataToApi));
 //Redirect to a Error Page
 var defaultUrlOptions = LinkManager.GetDefaultUrlOptions();
 defaultUrlOptions.SiteResolving = Settings.Rendering.SiteResolving;
 formSubmitContext.RedirectUrl = new UrlString(LinkManager.GetItemUrl(Sitecore.Context.Item, defaultUrlOptions)) + "?apierror=true";
 formSubmitContext.RedirectOnSuccess = true;
 formSubmitContext.Abort();

It Reloads the page but the querystring was not added ?

Any Help..

Property that you tries to use is considered to be used for Success form submit

formSubmitContext.RedirectUrl = new UrlString(LinkManager.GetItemUrl(Sitecore.Context.Item, defaultUrlOptions)) + "?apierror=true";
formSubmitContext.RedirectOnSuccess = true;

but, you abort context. It means that forms fails.

formSubmitContext.Abort();

You can try to use standard ASP.Net approach for redirect:

HttpContext.Current.Session.Abandon();
Response.Redirect(new UrlString(LinkManager.GetItemUrl(Sitecore.Context.Item, defaultUrlOptions)) + "?apierror=true", false);
