Qr reading with Opencv in real time Error "cv2.error: opencv(4.7.0)"

I was developing an application to log in and out times using a Qr.
The system runs but when it is sent to register the hours the camera turns on and after a while this error appears.
invalid qr code source points (expected: 'contourarea(src_points) > 0.0'), where > 'contourarea(src_points)' is 0 > must be greater than > '0.0' is 0.
This is the part of the code as I have done where the error occurs
while (capture.isOpened()):
_,frame = capture.read()
if (cv2.waitKey(1)== ord('s')):
break
qrDetector = cv2.QRCodeDetector()
data,bbox, rectifiedImage = qrDetector.detectAndDecode(frame)
fecha = date.today()
now = datetime.now()
h=now.time()
**if len(data) > 0:** #LINEA DONDE SALTA EL ERROR
arr = data.replace("\'", "\"")
arreglo = json.loads(arr)
cedula = arreglo["Cedula"]
nombre = arreglo["Nombre"]
sql ='SELECT asi_id,asi_estado FROM asistencia WHERE asi_id = (select MAX(asi_id)from asistencia WHERE asi_cedula = %s)'
cursor.execute(sql,(cedula,))
datos = cursor.fetchone()
id = datos[0]
estado = datos[1]
if(cedula == cedula and estado == None or estado != "Entrada" ):
asistencia.lbestado.setText("Entrada")
estado1 = "Entrada"
sqli = 'INSERT INTO asistencia(asi_cedula,asi_nombre,asi_hora_e,asi_fecha,asi_estado)VALUES(%s,%s,%s,%s,%s)'
datos = (cedula,nombre,h,fecha,estado1)
cursor.execute(sqli,datos)
db.connection.commit()
else:
asistencia.lbestado.setText("Salida")
estado2 = "Salida"
sql2 = 'UPDATE asistencia SET asi_hora_s = %s, asi_estado = %s WHERE asi_cedula = %s AND asi_id = %s'
d2 = (h,estado2,cedula,id)
cursor.execute(sql2,d2)
db.connection.commit()
winsound.Beep(f,d)
time.sleep(2)
else:
image = qimage2ndarray.array2qimage(frame)
asistencia.lbvista.setPixmap(QPixmap.fromImage(image))
The objective is to keep the camera on all the time until the user decides to exit by closing the application.

can't adapt type 'data'

I have data class:
class data:
def __init__(self, ReadTime, Concentration_PM10, Concentration_SO2, Concentration_O3, Concentration_NO2, Concentration_CO, AQI_PM10,
AQI_SO2,AQI_O3, AQI_NO2, AQI_CO, AQI_AQIIndex, AQI_ContaminantParameter, AQI_State, AQI_Color ):
self.ReadTime = ReadTime

self.AQI_AQIIndex = AQI_AQIIndex
self.AQI_ContaminantParameter = AQI_ContaminantParameter
self.AQI_State = AQI_State
self.AQI_Color = AQI_Color
I'm sending a request to an api and populating the variables into a list.:
list = []
for i in result:
list.append( data(i['ReadTime'], i['Concentration']['PM10'], i['Concentration']['SO2'],i['Concentration']['O3'],

i['AQI']['State'],i['AQI']['Color']))
then I want to insert this list into a table in PostgreSQL but I get error "can't adapt type 'data'"
list_record = ", ".join(["%s"] * len(list))
query_insert= (f"INSERT INTO hava_kalitesi (ReadTime, Concentration_PM10, Concentration_SO2, Concentration_O3, Concentration_NO2, Concentration_CO, AQI_PM10, AQI_SO2, AQI_O3, AQI_NO2, AQI_CO, AQI_AQIIndex, AQI_ContaminantParameter,AQI_State,AQI_Color) VALUES {list_record}"

In Odoo 10,how can I specify a data in create_date,create_uid,instead of value in system,when I use method named 'create' to create a record

I create new record with the method named create() in local database with data pulled away from remote database.As we all know,there are four normal fields in Odoo such as create_date,write_date,create_uid,write_uid.I want these data to be in a remote database，but when I use method named create() to create the record,these data are the data at the time of local creation and not the remote data.
For example,in remote database,the creat_date is '2019-10-11',I can't change the value that is finally written to the local database even if I pass the value of the remote database into the dictionary.Finally,the value of field named create_date is '2019-12-03' rather than '2019-10-11'.The '2019-12-03' is the date now.The situation is similar for other fields such as write_date,create_uid,write_uid.
Please help me,thanks to everyone who thought about this question.

You can change standart odoo fields after you create your record with sql query
property_id = self.env['report.rental.income.from.property'].create(value)
self.env.cr.execute("UPDATE report_rental_income_from_property SET create_date='%s', create_uid=%s, write_date='%s', write_uid=%s WHERE id=%s" %
(value['create_date'], value['create_uid'], value['write_date'], value['write_uid'], property_id))

Have a look to xlwt http://pypi.python.org/pypi/xlwt

You could directly write CSV from MySQL records,
import csv
csv_writer = csv.writer(open(FILENAME,'w'), delimiter=',',quotechar="'")
data = cursor.fetchall()
for row in data:
csv_writer.writerow(row)
Full example at
http://snipplr.com/view/11970/simple-csv-dump-script/
SELECTQ="SELECT * FROM category"
FILENAME="dump.csv"
import MySQLdb
import csv
db = MySQLdb.connect(host="localhost", user="root", passwd="", db="sakila")
dump_writer = csv.writer(open(FILENAME,'w'), delimiter=',',quotechar="'")
cursor = db.cursor()
cursor.execute(SELECTQ)
result = cursor.fetchall()
for record in result:
dump_writer.writerow(record)
db.close()
