Question

We are using DNN with 2sxc installed, and when we go to a URL where we would expect to see a page with content on our website, we see the following error message. Please can someone tell us what is wrong and how to fix it? Thank you in advance.

Error: System.NullReferenceException: Object reference not set to an instance of an object. at ToSic.Sxc.Data.DynamicEntity.get_EntityTitle() in C:\Projects\2sxc\2sxc\Src\Sxc\ToSic.Sxc\Data\DynamicEntity\DynamicEntity.cs:line 61 at ASP._Page_Portals_0_2sxc_Newsroom__SharingButtons_cshtml.Execute() in n:\APSDNN\Portals\0\2sxc\Newsroom_SharingButtons.cshtml:line 84 at System.Web.WebPages.WebPageBase.ExecutePageHierarchy() at System.Web.WebPages.WebPageBase.ExecutePageHierarchy(WebPageContext pageContext, TextWriter writer, WebPageRenderingBase startPage) at System.Web.WebPages.WebPageBase.<>c__DisplayClass7.b__6(TextWriter writer) at System.Web.WebPages.WebPageBase.Write(HelperResult result) at ASP._Page_Portals_0_2sxc_Newsroom__IndividualArticle_cshtml.Execute() in n:\APSDNN\Portals\0\2sxc\Newsroom_IndividualArticle.cshtml:line 254 at System.Web.WebPages.WebPageBase.ExecutePageHierarchy() at System.Web.WebPages.WebPageBase.ExecutePageHierarchy(WebPageContext pageContext, TextWriter writer, WebPageRenderingBase startPage) at ToSic.Sxc.Engines.RazorEngine.Render(TextWriter writer) in C:\Projects\2sxc\2sxc\Src\Dnn\ToSic.Sxc.Razor\Engines\Razor\RazorEngine.cs:line 72 at ToSic.Sxc.Engines.RazorEngine.RenderTemplate() in C:\Projects\2sxc\2sxc\Src\Dnn\ToSic.Sxc.Razor\Engines\Razor\RazorEngine.cs:line 82 at ToSic.Sxc.Engines.EngineBase.Render() in C:\Projects\2sxc\2sxc\Src\Sxc\ToSic.Sxc\Engines\EngineBase.cs:line 147 at ToSic.Sxc.Blocks.BlockBuilder.RenderInternal() in C:\Projects\2sxc\2sxc\Src\Sxc\ToSic.Sxc\Blocks\BlockBuilder_Render.cs:line 113

Originally, we had an app with inputs and we input content data that would output a formatted out web page, but it seems to have become broken somehow, sometime after it's creation/posting/publishing.

Answer 1

It appears that on n:\APSDNN\Portals\0\2sxc\Newsroom_IndividualArticle.cshtml:line 254 you are accessing something like Content.EntityTitle or something, but Content (or whatever name it has) is null. Find out where the main object comes from, and why it's empty.
