I use cocotb 1.6.2 to test the Bus.driver()

module dut(
    input [7:0] data_in_data0,
    input [7:0] data_in_data1,
    output logic  [7:0] data_out_data0,
    output logic  [7:0] data_out_data1
);
always_comb begin
    data_out_data0=data_in_data1;
    data_out_data1=data_in_data0;
end
endmodule

class dataPkg(object):
    def __init__(self,data0,data1) -> None:
        self.data0=data0
        self.data1=data1

@cocotb.test()
async def testDemo(dut):
    dataIn=Bus(dut,"data_in",["data0","data1"])
    await Timer(1,'ms')
    dataIn.drive(dataPkg(5,6))
    await Timer(1,'ms')

the data_in_data0 and data_in_data1 are not assigned by 5 and 6.the Bus.drive() not work
