getting "Error on reading from the event loop self pipe" error

Question

I am looking to write a program to filter out and analyze PCAP file.

Here is my current code, which is throwing an error.

import pyshark
import asyncio

pcap_file = 'c:/sip.cap'

capture = pyshark.FileCapture(pcap_file,display_filter='sip contains factory')
for packet in capture:
    try:
        if hasattr(packet, 'sip'):
            field_names = packet.sip._all_fields
            field_values = packet.sip._all_fields.values()
            for field_name, field_value in zip(field_names, field_values):
                if field_name == 'sip.msg_hdr':
                    print(str(field_value.split('\\xd\\xa')))
                elif field_name == 'sip.msg_body':
                    print(field_value)
    except OSError:
        pass
    except asyncio.TimeoutError:
        pass

This error is being thrown:

Close the file capture object "capture".

The last line in the try block:

capture.close()
