Bug: Ollama connector fails when calling plugin functions that have parameters with Guid type

[nitrovent]

Describe the bug Function call fails when trying to call function that has guid parameter:

fail: Microsoft.SemanticKernel.KernelFunction[0]
      Function TodoPlugin-SetCompleted failed. Error: No converter found to convert from System.Guid to System.Text.Json.JsonElement. (Parameter 'id')
      Actual value was 9416a630-d9ca-45d0-bf02-3f8d0d3e17bb.
      System.ArgumentOutOfRangeException: No converter found to convert from System.Guid to System.Text.Json.JsonElement. (Parameter 'id')
      Actual value was 9416a630-d9ca-45d0-bf02-3f8d0d3e17bb.

To Reproduce Steps to reproduce the behavior:

1. Add plugin with function with guid parameter, in my case:

   [KernelFunction, Description("Set the completed state of a todo")]
   public void SetCompleted(
   [Description("Determines the id of the todo to toggle")] Guid id, 
   [Description("Determines whether to to complete or to resume the todo")] bool complete = true) 
   { 
   //...
   }

2. Give instructions that will call the function

Expected behavior Function calls work with functions with guid parameters

Platform

• Language: C#
  • Source: Nuget dotnet-1.29.0

Additional context Works well with the Azure connector.

Edit because I thought I it was with a boolean parameter. I am sure I saw that error for boolean, too when testing.
