Assuming you are building everything from source, would you mind changing all references where CheckCertificateRevocationList = true to CheckCertificateRevocationList = false:

Then func start KernelHttpServer and try the web app again.

Mar 30 '23 00:03 craigomatic

@craigomatic Thanks for your reply. I change all references as follow, but still doesn't work (still 400 as above):

Mar 30 '23 03:03 rust17

Hmm, ok thank you for trying that.

Would it be possible to get a stack trace from the KernelHttpServer?

From memory the client app is only getting the top level error message, so there is likely some more interesting detail in the stacktrace we can use to track this down.

Mar 30 '23 04:03 craigomatic

Sorry. I'm not familiar with .NET. How can I get a stack trace from the KernelHttpServer?

Mar 30 '23 07:03 rust17

@rust17 thank you for the bug info here, we will take a look at this.

@evchaki Thanks for your reply. It’s possible that my location may have restrictions on accessing certain websites. I tried to use a proxy to access and forward all requests through the local port 1087, but it failed when starting func start --csharp. The failure log is as follows:

@craigomatic can you take a look at this?

May 16 '23 20:05 evchaki

I have the same problem

May 18 '23 15:05 PaulC-F1000

This has been a tricky one to repro at this end.

Could I ask for someone on the thread experiencing the issue to try and repro with one of the simpler samples, ie: https://github.com/microsoft/semantic-kernel/blob/main/samples/dotnet/kernel-syntax-examples/Example04_CombineLLMPromptsAndNativeCode.cs

I think it will result in the same error, however it will allow us to remove Azure Functions from the list of potential contributors to the issue.

May 18 '23 19:05 craigomatic

@craigomatic, I edit the samples/dotnet/kernel-syntax-examples/Program.cs like this: Then,

dotnet run Program.cs

outputs:

Thank you for trying this, may I ask if you had a valid Bing key setup before running the sample?

I believe the 401 you are getting is the Bing API complaining about the absence of an API key.

May 30 '23 22:05 craigomatic

@craigomatic I got the key from https://www.bing.com/webmasters. Can you tell me how to get a valid Bing key?

Jun 07 '23 02:06 rust17

You should be able to get a bing web api key via https://www.microsoft.com/en-us/bing/apis/bing-web-search-api

Jun 07 '23 14:06 craigomatic

@rust17 were you able to try this with a key via the link above?

Anyone else on the thread still seeing this issue and/or willing to try the smaller sample suggested above?

Jun 14 '23 16:06 craigomatic

@craigomatic To get a key, I need to bind a master card, which is too difficult for me.
