python3 - Can't convert 'bytes' object to str implicitly

Question

I'm trying to send a list over a socket connection, but I'm hitting a Can't convert 'bytes' object to str error.

while True:
    try: 
        data = stream.read(CHUNK)
    except IOError: 
        pass
    else:
        decoded = numpy.fromstring(data, dtype=numpy.float32)
        i = json.dumps(decoded.tolist())
        jsonDecoded = json.loads(i)
        jsonS = "%s" % jsonDecoded
        ws.send(jsonS)

I also tried jsonS = "{}".format(jsonDecoded, 'utf-8') as well as "".join(str(x) for x in jsonDecoded), which gives me the same error. str(jsonDecoded, 'utf-8') doesn't work either.

Any ideas?

Here is the full stacktrace
