[SOLVED] Why MassTransit throws an error when I use IRequestClient to get result from state machine

I try to get state machine result through API using MediatR pattern but I get a timeout exception and finally 404 - I wonder what I was doing wrong here.

namespace Play.Trading.Purchases.GetPurchase
{
    public record GetPurchaseStateCommand(Guid CorrelationId) : ICommand<GetPurchaseStateResult>;

    public record GetPurchaseStateResult(PurchaseDto PurchaseDto);

    public class GetPurchaseStateHandler(IRequestClient<GetPurchaseState>) : ICommandHandler<GetPurchaseStateCommand, GetPurchaseStateResult>
    {
        public async Task<GetPurchaseStateResult> Handle(GetPurchaseStateCommand command, CancellationToken cancellationToken)
        {
            var response = await purchaseClient.GetResponse<PurchaseState>(new GetPurchaseStateRequest(command.CorrelationId), cancellationToken);

            if (response.Message.CorrelationId  != command.CorrelationId) 
                throw new NotFoundException($"No data with {command.CorrelationId} was fpund");

            return new GetPurchaseStateResult(new PurchaseDto(response.Message.UserId,
                response.Message.ItemId, response.Message.PurchaseTotal, response.Message.Quantity,
                response.Message.CurrentState, response.Message.ErrorMessage, response.Message.Received, response.Message.LastUpdated));
        }
    }
}

I was expecting to get results as per data that saved in database but I get the following errors after I consume my API:

System.InvalidOperationException: The exception handler configured on ExceptionHandlerOptions produced a 404 status response. This InvalidOperationException containing the original exception was thrown since this is often due to a misconfigured ExceptionHandlingPath. If the exception handler is expected to return 404 status responses then set AllowStatusCode404Response to true.
