[Python] how to send a can bus message with 2 seconds between spaces in python-can

I want to be able to send a message on canbus one with 2 seconds between them

have tried some python can examples with the same result can send and receive with python-can code

now I don't know if I'm doing something wrong or the code

run with a raspberry pi 4b with a can bus module mcp2515 os bookworm 64bit have installed python-can 4.5

import can

with can.interface.Bus(interface="socketcan", channel="can0") as bus:
msg = can.Message(
arbitration_id=0x020,
data=[0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07],
is_extended_id=False
)

task = bus.send_periodic(msgs=msg, period=1)


Exception has occurred: CanOperationError
Couldn't send CAN BCM frame due to OS Error: Invalid argument You are probably referring to a non-existing frame. [Error Code 22]
OSError: [Errno 22] Invalid argument

The above exception was the direct cause of the following exception:

File "/home/pican/foobar/project/test_5.py", line 7, in <module>
task = bus.send_periodic(msgs=msg,period=1,store_task=True)
