Okay, so I managed to resolve this error by add decode_response = true to redis.StrictRedis.from_url function
Here's what I changed

self._r = redis.StrictRedis.from_url(current_app.config['REDIS_URL'])
has been changed to
self._r = redis.StrictRedis.from_url(current_app.config['REDIS_URL'], decode_responses=True)

What I understood from the problem was that redis is sending the response in bytes and it has to be decoded to a relevant form. I am completely new to Redis and Python so please bear with me.
