When I use with flask, I got a error

[Aleftherian]

My code:

from hcaptcha.hcaptcha import HCaptchaVerifier, HCaptchaVerificationError
hcaptcha_client = HCaptchaVerifier(secret_key="")

@public_blueprint.route('/signup', methods=['GET', 'POST'])
def signup():
	if request.method=="POST":

		hcatpcha_token=request.form.get('hcatpcha_token')
		nickname=request.form.get('nickname')

		nombre=request.form.get('name1')
		apellido=request.form.get('name2')

		email=request.form.get('email')
		password=request.form.get('password')

		try:
			is_valid = asyncio.run(hcaptcha_client.verify(hcatpcha_token))
			if is_valid:
				cuenta=Accounts(username="", password=password, gmail=email, number="", nombre=" ", apellido="", genero="", fecha_nacimiento="", fecha_registro=datetime.now(), VIP="")
				db.session.add(cuenta)
				db.session.commit()
			else:
				print("Captcha INvalido")
				return render_template('public/signup.html', msg="No haz completado el captcha!")
		except Exception as e:
			return e

	return render_template('public/signup.html', msg="Hello World")

I post to /signup
