.Net: Bug: OpenAPI plugin Converter issue

[AlexandruRus23]

Describe the bug
OpenAPI function erroring when invoked.

Error message:

Argument type 'System.Text.Json.JsonElement' is not convertible to parameter type 'integer'. (Parameter 'skip')
Actual value was 0. (Parameter 'skip')
Actual value was 0.

To Reproduce
Steps to reproduce the behavior:

1. Define an endpoint for an OpenAPI plugin like the following:

[HttpGet("bookings")]
[SwaggerOperation(OperationId = "GetBookings", Summary = "Returns a list of bookings. Supports 'skip' and 'take' query parameters for paging.")]
[ProducesResponseType(typeof(IEnumerable<BookingDto>), StatusCodes.Status200OK)]
public IActionResult GetBookings(
	[FromQuery][SwaggerParameter("The number of bookings to skip.")] int? skip = null,
	[FromQuery][SwaggerParameter("The maximum number of bookings to return.")] int? take = null)
{
	IEnumerable<BookingDto> bookings = _bookings;
	if (skip.HasValue && skip.Value > 0)
	{
		bookings = bookings.Skip(skip.Value);
	}
	if (take.HasValue && take.Value > 0)
	{
		bookings = bookings.Take(take.Value);
	}
	return Ok(bookings.ToList());
}

Later edit: I apologise for the badly formatted code, not sure how to fix it.

Expected behavior
Parameter conversation to work and the function to be invoked successfully

Additional context

This seems to only be an issue when registering IChatClient (MEAI) in the Kernel. If I use AddAzureOpenAIChatCompletion it works fine.

I've also seen errors around converting booleans.
