Python: Kernel Function Selection Strategy Assertion Error

[corytomlinson]

Not sure if this one is a bug or by design or just functionality not there yet in SK.

I am trying to use a custom KernelFunctionSelectionStrategy and bumping up against an assertion error related to assert isinstance(self.items[0], FunctionResultContent)

It seems that SK is expecting assistant messages to only be function call results (rather than text content).

The context is I have an orchestration kernel with an AzureChatCompletion service. I'm creating a KernelFunctionFromPrompt that contains the custom selection strategy for multiple AzureAssistantAgents.

The first 2 turns of the selection strategy work as expected, but then I run into this assertion error. Any help or guidance with custom selection strategies would be appreciated. Or if this is a bug or missing functionality, I will stop banging my head against the wall trying to make it work.
