Error using HttpModules in ASP.NET

It turns out that I'm using httpModules to handle the AuthenticateRequest and AuthorizeRequest events in the application. In the web.config I have it linked in the following tags:

<system.webServer>
    <modules>
         <add type="Proyecto.App.UI.CustomAuthenticationModule" name="CustomAuthenticationModule"/>
    </modules>
</system.webServer>

The project has no compilation errors, so it runs correctly. However, I'm getting the error in the front-end, and the browser console (Google Chrome) throws the following:

This causes events with ajax to not work (autocomplete in textbox).

What am I doing wrong? When you remove the httpModules, the application works correctly.

Greetings and I hope you can help me.

with what type of channel do you have your App Pool configured?

If you use Classic Channeling then you must define your HttpModule in the web.config in the following way

<configuration>
    <system.web>
        <httpModules>
            <add type="Proyecto.App.UI.CustomAuthenticationModule" name="CustomAuthenticationModule"/>
        </httpModules>
    </system.web>
</configuration>

If you use Integrated Channeling then you must define your HttpModule in the web.config as follows

<configuration>
    <system.webServer>
        <modules>
            <add type="Proyecto.App.UI.CustomAuthenticationModule" name="CustomAuthenticationModule"/>
        </modules>
    </system.webServer>
</configuration>

I would also check if you have established in your web.config both the HttpHandler and the HttpModule for the AJAX configuration (check the version numbers you work with)

<configuration>
    <system.web>
        <httpHandlers>
            <remove verb="*" path="*.asmx"/>
            <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
            <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
            <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
        </httpHandlers>
        <httpModules>
            <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
        </httpModules>
    </system.web>
</configuration>
