If you want to see the error page when you run the project from Visual Studio, you have to set the mode to ON.

<customErrors mode="On" defaultRedirect="error.htm">

When you set mode to RemoteOnly, it renders error pages to external users alone.

Refer this MSDN article for more details:

ASP.NET handlers are not called for non-asp.net files.you can force the asp.net handler to operate on all requests by setting runAllManagedModulesForAllRequests as true in your web config as below

HTML

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
</system.webServer>

check : 404 Redirecting for non aspx pages[^]
