Pyshark: RunTimeError raised upon completion of sniff_continuously for loop

I'm writing a test using Pyshark that starts a live capture, uploads a file using ftps, and then loops through the packets and looks for certain attributes. This is the snippet that is failing



cap = pyshark.LiveCapture(interface='ethernet', bpf_filter='src 10.200.150.200', output_file='pyshark.pcap')

ftps.storbinary('STOR block_01.log', file_to_upload)

for packet in cap.sniff_continuously(packet_count=200):
if 'IP' in packet:
packet_result = print_dcsp_info(packet)
if packet_result:
count += 1
print(packet['ip'])
if count == 5:
print('Test PASSED')
else:
print('aint it')
file.close()
cap.close()
ftps.quit()


At the end of the loop I am getting this error



> "C:UsersRivetAppDataLocalProgramsPythonPython37libsite-packagespysharkcapturecapture.py:229:
> RuntimeWarning: coroutine 'wait_for' was never awaited
> self.eventloop.run_until_complete(self._cleanup_subprocess(tshark_process))
> C:UsersRivetAppDataLocalProgramsPythonPython37libsite-packagespysharkcapturecapture.py:229:
> RuntimeWarning: coroutine 'Process.wait' was never awaited
> self.eventloop.run_until_complete(self._cleanup_subprocess(tshark_process))"


This happens every time I run this and I cannot seem to find a fix. I found similar issues (https://github.com/KimiNewt/pyshark/issues/297 and OSX PyShark: RuntimeWarning: coroutine 'wait_for' was never awaited), but no answers yet.
