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)

"[ERROR] OSError: [Errno 38] Function not implemented" - Accessing trend deepsecurity.ComputersApi via Lambda

I have written a python script that successfully queries the trend deepsecurity api calls when ran locally on my machine.
I've been tasked with running the script in an aws lambda so that it is automated and can be scheduled.
The script is following the examples in the api reference and calls the legacy api successfully. However when I attempt to query using the computers api It blows up on the line : computers_api = deepsecurity.ComputersApi(deepsecurity.ApiClient(configuration))
def get_computer_status_api():
# Include computer status information in the returned Computer objects
#expand = deepsecurity.Expand(deepsecurity.Expand.computer_status)
expand = deepsecurity.Expand()
expand.add(deepsecurity.Expand.security_updates)
expand.add(deepsecurity.Expand.computer_status)
expand.add(deepsecurity.Expand.anti_malware)
# Set Any Required Values
computers_api = deepsecurity.ComputersApi(deepsecurity.ApiClient(configuration))
try:
computers = computers_api.list_computers(api_version, expand=expand.list(), overrides=False)
print("Querying ComputersApi...")
api_response_str=str(computers)
computer_count = len(computers.computers)
print(str(computer_count) + " Computers listed in Trend")

the error I get is :

searching for this error it implies that I can't use the deepsecurity api in a lambda because lambdas don't support multiprocessing.
Looking for either confirmation that this is the case or suggestions for what I can change to get this working.
Trend support ticket suggested posting to here.

Resolved the issue by changing the python version from 3.8 to 3.7 in the lambda. The script now runs successfully

Reading emails using poplib throws an error - poplib.error_proto: -ERR EOF

I am trying to read emails using the poplib library but getting an error - poplib.error_proto: -ERR EOF. The initial connection seems to be successful and I am able to get the response for the getwelcome() function but after that, the server seems to be closing the connection. Adding the code below, nothing special just the dummy code -
import poplib
client = poplib.POP3_SSL(server_name, port)
client.user(username)
client.pass_(password)
welcome = client.getwelcome()
print(welcome)
messages = len(client.list()[1]) # throws error - poplib.error_proto: -ERR EOF
Traceback (most recent call last):
File "email-pop.py", line 68, in <module>

File "email-pop.py", line 36, in fetch_all_mails
numMessages = len(pop_conn.list()[1])
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/poplib.py", line 243, in list

if not line: raise error_proto('-ERR EOF')
poplib.error_proto: -ERR EOF
Can't seem to find what could be the issue, any help would be appreciated.
Thanks

google-api-python-client broken because of OAuth2?

I am trying to check if a certain dataset exists in bigquery using the Google Api Client in Python. It always worked untill the last update where I got this strange error I don't know how to fix:

AssertionError: PID check failed. RNG must be re-initialized after fork(). Hint: Try Random.atfork()
Is someone understanding what is hapening?
Note that I also get this error with other bricks like GCStorage.
Note also that I use the following command to load my Google credentials:
from oauth2client.client import GoogleCredentials
def get_credentials(credentials_path): #my json credentials path
logger.info('Getting credentials...')
try:
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = credentials_path
credentials = GoogleCredentials.get_application_default()
return credentials
except Exception as e:
raise e
So if anyone know a better way to load my google credentials using my json service account file, and which would avoid the error, please tell me.

It looks like the error is in the PyCrypto module, which appears to be used under the hood by Google's OAuth2 implementation. If your code is calling os.fork() at some point, you may need to call Crypto.Random.atfork() afterward in both the parent and child process in order to update the module's internal state.
See here for PyCrypto docs; search for "atfork" for more info:
https://github.com/dlitz/pycrypto
This question and answer might also be relevant:
PyCrypto : AssertionError("PID check failed. RNG must be re-initialized after fork(). Hint: Try Random.atfork()")

'NoneType' object has no attribute 'promotePrefixes'

So initially I connect to a server with:
soapclient = Client(url, transport=WindowsHttpAuthenticated(username=user, password=passwd))
and this works fine because when I print it it shows all of its properties correctly.
Then I run:
request = self.soapclient.factory.create('ns3:CRRequest')
request['ChangeRequestId'] = '601904'
response = self.soapclient.service.GetChangeRequestById([request])
And then I get an error on the response line which reads:
Traceback (most recent call last):
File "C:\Users\nlujan\Desktop\prism_source.py", line 63, in <module>
CR = prism.getChangeRequestById('601904')

AttributeError: 'NoneType' object has no attribute 'promotePrefixes'
I had someone else run my script and it works fine on their computer but I keep getting an error in mine. I've installed several different versions of python to see if that's the problem but with no luck. Does anyone see what could be the problem?

Try to add an endpoint address
client = Client('url', location = "https://someurl/services")
