Error 404 Client Error

[l0rddarkf0rce]

I have the following simple code

import upnpclient
def findWiiM():
    WiiMServer = None
    devices = upnpclient.discover()
    for dev in devices:
        if dev.friendly_name == 'WiiM Mini':
            WiiMServer = dev.location
    return WiiMServer

print(findWiiM())

and when I run it I get the following error?

Error '404 Client Error: Not Found for url: http[:]//192.168.1.220:8060/dial/ecp_SCPD.xml' for <upnpclient.ssdp.Entry object at 0x000001F68CB1E310>

Any ideas on how to ignore and/or fix it?

The error occurs by just running upnpclient.discover()

Same error here.

Ugly workaround: temporarily redirect stderror to /dev/null:

safe_stderr = sys.stderr
sys.stderr = open(os.devnull,'w')
devices = upnpclient.discover()
sys.stderr = safe_stderr

[sanderjo]

I assume the error is from:

https://github.com/flyte/upnpclient/blob/develop/upnpclient/ssdp.py#L126

I'm not sure, but maybe you can overwrite that ... ?

        log = _getLogger("ssdp")
        log.error("Error '%s' for %s", exc, entry)

EDIT:
Commenting out that line in .local/lib/python3.8/site-packages/upnpclient/ssdp.py indeed avoids the error message

[sanderjo]

Any feedback on this?

Anything better than the workaround below?

#!/usr/bin/env python3

import upnpclient
import sys, os

# workaround: redirect stderr
safe_stderr = sys.stderr
sys.stderr = open(os.devnull,'w')
devices = upnpclient.discover()
sys.stderr = safe_stderr

for i in devices:
	print(i)
	try:
		print(i.WANIPConn1.GetExternalIPAddress())
	except:
		pass
