Asn1 parsing error when trying to connect to mongo atlas

I am using MongoDB atlas for my discord bot but recently ran into an error. On the hosting (Heroku) everything works without errors, I first updated all the modules, but the error has not disappeared.
I am using motor as a driver to work with MongoDB atlas.
Checked the database connection URL, everything is correct.
Python version 3.10(on Heroku too)

ValueError: error parsing asn1 value: ParseError { kind: InvalidValue, location: ["RawCertificate::tbs_cert", "TbsCertificate::serial"] }

I've solved my problem getting the parsing asn1 value error by adding the ssl_cert_reqs option on the MongoClient (and obviously importing ssl).
dbClient = pymongo.MongoClient(uri, ssl_cert_reqs=ssl.CERT_NONE)

How to add constraints in client.services.create while creating a new service in existing docker swarm Python Docker SDK?

I want to create a service in existing swarm network using python docker sdk. I have a swarm network named test_net.
Installation of library : pip3 install docker
Below is the code used for creating the service
import docker
from docker.types import RestartPolicy, Placement
def python_sdk():
client = docker.DockerClient(base_url='unix://var/run/docker.sock')
service_created = client.services.create(
image='python:3.7-alpine',
command='python /home/ubuntu/python.py',
constraints=Placement(constraints=['worker']),
mounts='/home/ubuntu/deployment/python.py:/home/ubuntu/python.py:rw',
networks=['test_net'],
restart_policy=RestartPolicy(condition='none'),
name='python_sdk'
)
print("Created service : ", service_created)
Below is the error which I got by executing above code :
Traceback (most recent call last):

docker.errors.APIError: 400 Client Error for http+docker://localhost/v1.41/services/create: Bad Request ("json: cannot unmarshal object into Go struct field Placement.TaskTemplate.Placement.Constraints of type []string")
I am referring to this documentation.
How can I use Placement object to use constraints?
I also tried constraints = ["Placement(constraints=['worker']"]

I got the answer for the above issue. In the documentation, it is mentioned that the list of str needs to be passed in constraints.
The mentioned parameter is documentation : constraints (list of str) – Placement constraints.
So the final code will be,
import docker
from docker.types import RestartPolicy, Placement
def python_sdk():
client = docker.DockerClient(base_url='unix://var/run/docker.sock')
service_created = client.services.create(
image='python:3.7-alpine',
command='python /home/ubuntu/python.py',
constraints=['node.role == worker']),
mounts='/home/ubuntu/deployment/python.py:/home/ubuntu/python.py:rw',
networks=['test_net'],
restart_policy=RestartPolicy(condition='none'),
name='python_sdk'
)
print("Created service : ", service_created)

Error while building a RESTApi using flask_restful

Flask RESTApi newbie here
I am trying to build a RESTapi service in Flask (and I am trying to save the output as a .txt file) using flask_restful for a code of mine using the pydifact module as follows:
import datetime
from pydifact.message import Message
from pydifact.segments import Segment
from flask import Flask, request
from flask_restful import Resource, Api
app = Flask(__name__)
api = Api(app)
class RestAPI(Resource):
def get(self, ABSENDER_ID, EMPFÄNGER_ID, ERSTELLUNG_DATUM_ZEIT, REFERENCE):
MSCONS = Message()
def erstellung_datum_zeit(dt_time):
# Needed for the UNB segment
dt_time = dt_time.strftime('%Y%m%d%H%M')
return dt_time
def UNA_UNB_segment(absender_id, empfänger_id, erst_datum, ref):
MSCONS.add_segment(Segment('UNA', ":+.? '"))
MSCONS.add_segment(Segment('UNB', ['UNOC', '3'], [absender_id, '14'], [
empfänger_id, '500'], [erst_datum[2:8], erst_datum[8:]], ref, '', 'TL'))
ERSTELLUNG_DATUM_ZEIT = str(
erstellung_datum_zeit(datetime.datetime.now()))
UNA_UNB_segment(ABSENDER_ID, EMPFÄNGER_ID,
ERSTELLUNG_DATUM_ZEIT, REFERENCE)
result = MSCONS.serialize()
final_result = result
PATH_FOR_TXT = r'C:\Users\kashy\OneDrive\Desktop\Codes\mscons.txt'
textfile = open(PATH_FOR_TXT, 'w')
textfile.write(result)
textfile.close()
return {'result': final_result}
api.add_resource(
RestAPI,
'/RestAPI/<int:ABSENDER_ID>/<int:EMPFÄNGER_ID/<int:ERSTELLUNG_DATUM_ZEIT/<int:REFERENCE>')
if __name__ == '__main__':
app.run(debug=True)
The ABSENDER_ID, EMPFÄNGER_ID, ERSTELLUNG_DATUM_ZEIT, REFERENCE should all be user inputs and they should be all in string format.
When I do /RestAPI/<str:ABSENDER_ID>/<str:EMPFÄNGER_ID/<str:ERSTELLUNG_DATUM_ZEIT/<str:REFERENCE>, i get the following error:

ValueError: malformed url rule: '/RestAPI/<int:ABSENDER_ID>/<int:EMPFÄNGER_ID/<int:ERSTELLUNG_DATUM_ZEIT/<int:REFERENCE>'
I am totally new to this and just started learning it using the Building a REST API using Python and Flask | Flask-RESTful tutorial.
Can anyone please tell me what is the mistake I am doing?

Your url routes have problem. In the first one, it should be string instead of str and in the second one you have a missing > at the end of int:EMPFÄNGER_ID and int:ERSTELLUNG_DATUM_ZEIT
Correct ones should be:
/RestAPI/<string:ABSENDER_ID>/<string:EMPFANGER_ID>/<string:ERSTELLUNG_DATUM_ZEIT>/<string:REFERENCE>
and
/RestAPI/<int:ABSENDER_ID>/<int:EMPFANGER_ID>/<int:ERSTELLUNG_DATUM_ZEIT>/<int:REFERENCE>
Note: I replaced Ä with A in urls above because that might also cause malformed url rule issue.

Python Geocoders Not Working

I am unable to unserstand this problem, and have a close to no knowledge about SSL and its errors.
I dont know, how relevant it is, but the app was working until I installed Redis Server for another app in the same project. I have uninstalled it, but it is still not working.
Lastly, No other Geocoder is working - Every geocoder gives the same error. I tried to use GeoPy, geocoder 1.6.4
Thanks in advance
