TypeError: expected string or bytes-like object
Hi,
I'm trying to use the match function with the following...
import osrm
OSRM_AUTH=('user', 'pass')
OSRM_VERSION = 'v1'
OSRM_PROFILE = 'driving'
OSRM_HOST = 'http://router.project-osrm.org'
osrm.RequestConfig.host = OSRM_HOST
osrm.RequestConfig.version = OSRM_VERSION
osrm.RequestConfig.profile = OSRM_PROFILE
# osrm.RequestConfig.auth = OSRM_AUTH
points = [(-33.45017046193167,-70.65281867980957),

(-33.453867464504555,-70.65277576446533)]
result = osrm.match(points, steps=False, overview='simplified', url_config=osrm.RequestConfig)
This fails with when calling request.py with HTTPError: HTTP Error 400: Bad Request...

I've checked type(req) that is passed to urlopen(req) and its reported as a string so I'm stumped as to whats going wrong here.
If I try defining a custom RequestConfig() I get an HTTPError: HTTP Erro 400: Bad Request again...

I'm doing this all under a Conda Virtual Environment that is based on Python 3.8.
Any advice/insight would be very much appreciated as I'm stumped as to how to work out where things are going wrong.
Thanks in advance.
