Uno 6.3 .NET 10

I'm using an API client generated from Kiota and when I do an API request I get a html response.

<!DOCTYPE html>

<meta name="mobile-web-app-capable" content="yes">

</head>
<body>
    <div id="uno-body" class="container-fluid uno-body">
        <div class="uno-loader"
             loading-position="bottom"
             loading-alert="none">

            <!-- Logo: change src to customize the logo -->
            <img class="logo"
                 src=""
                 title="Uno is loading your application" />

            <progress></progress>
            <span class="alert"></span>
        </div>
    </div>
    <noscript>
        <p>This application requires Javascript and WebAssembly to be enabled.</p>
    </noscript>
</body>
</html>

This is what I get from API. I can't find a sample for using Kiota extension either. Has anyone encountered this before?

Configuration as reference

services.AddKiotaClient<MyServiceClient>(
    context,
    options: new EndpointOptions { Url = context.Configuration["ApiClient:Url"]! }
);
