"quart_session" TypeError: cannot use a string pattern on a bytes-like object

sessions.py
if self.use_signer:
session_id = self._get_signer(app).sign(want_bytes(session.sid))
else:
session_id = session.sid
response.set_cookie(cname, session_id,
expires=expires, httponly=httponly,
domain=domain, path=path, secure=secure, samesite=samesite)
set_cookie not allowed a byte type value, have to decode to str type：session_id = session_id.decode('utf-8')

I am a student, when I add this session_id = session_id.decode('utf-8')，it work。。。。am i right？

[zrorolocete]

sorry It work just for the first time, then crash.....
my code is

app = Quart(name)
app.config['PERMANENT_SESSION_LIFETIME'] = timedelta(days=30)
app.config['SESSION_COOKIE_SECURE'] = True
app.config['SESSION_COOKIE_HTTPONLY'] = True
app.config['SESSION_COOKIE_SAMESITE'] = 'Strict'
app.config['SESSION_TYPE'] = 'redis'
Session(app)

the original error is
TypeError: cannot use a string pattern on a bytes-like object

I cannot find the error place
