Doconut stop working after upgrade and new license

Doconut Product Family

I am now getting this error after upgrading our asp.net core project to 25.5.0

Init error. Please make sure your Startup.cs has the Doconut middleware declared. Handler is: /DocImage.axd

Even though in program.cs I have this code snippet

app.MapWhen(
    context => context.Request.Path.ToString().EndsWith("DocImage.axd"),
    appBranch =>
    {
        appBranch.UseDoconut(new DoconutOptions { UnSafeMode = false, ShowDoconutInfo = false });
    }
);

This used to work fine before.

Then it redirects to:

This localhost page can’t be found

No webpage was found for the web address: https://localhost:5001/DocImage.axd?Init=1&Zoom=75&token=&rnd=121753351691027&format=png

downgraded to 25.1.0.0 and get this addition error message

Return: Doconut 25.1.0.0 is running on localhost:5001. Error: Cannot read properties of undefined (reading ‘childNodes’)

Hi @Vametric01,

Thank you for the detailed information.

Please note that the error you’re experiencing is not related to the license or the new version 25.5.0, but most likely due to a configuration issue in your project.
