Describe the bug In any C# notebook if step has ".InvokeAsync" It errors with "Error: Invalid request: The request is not valid, HTTP status: 404"

Desktop (please complete the following information):

• OS: Windows
• IDE: VS Code
• NuGet Package Version "nuget: Microsoft.SemanticKernel, 0.15.230531.5-preview"

Thank you

Hey @Ofer-Gal, a 404 typically indicates that you haven't configured your AI settings right.

Can you verify that you have a settings.json file under the /samples/notebooks/dotnet/config directory?

It should look like this but populated with your correct values. { "type": "", "model": "", "endpoint": "", "apikey": "", "org": "" }

Also, the Jupyter notebooks still use TextCompletion models (as opposed to ChatCompletion models), so make sure you're using a supported model, typically this is text-davinci-003.

You can also verify that everything is populated correctly by looking at the Notebook variables:

Just click on the Variables button at the top of the Notebook in VSCode

And it should open a tab in terminal. Your variables should be populated as follows after you run the InvokeAsync function (this is from Notebook 02-running-prompts-from-file)

text-davinci-003

I changed the model in settings.json to text-davinci-003 and the results came back. Thank you. But the next section #!set --value @csharp:result --name result caused the error you see bellow. What does this statement do?

@Ofer-Gal What notebook are you in? Can you share a screenshot of the current failing steps, its output, as well as the state of the step before it?

Also, what kernel are you using to run the notebooks, .NET Interactive?

[Ofer-Gal]

00-getting started The state before was successful using .NET Interactive yes

[teresaqhoang]

@Ofer-Gal I think you may have added that section accidentally, as we don't have that in our samples: https://github.com/microsoft/semantic-kernel/blob/main/samples/notebooks/dotnet/00-getting-started.ipynb

You can either delete that section altogether, or if you don't have any other changes, you can reset the repo state by:

1. git checkout main
2. git restore . Then you should have a fresh slate to run the notebooks!

[Ofer-Gal]

Thanks
