How to Rabbitmq Connection Close - rabbitmq

Question

I am using Pika 1.1.0, Python 3.7.4. There is consumer in the thread. I want to kill the thread and close the rabbitmq connection, but it fails. Where am I doing wrong? How can I do it?
Error: pika.exceptions.StreamLostError: Stream connection lost: IndexError('pop from an empty deque')
def BrokerConnection(username, password):
try:
credentials = pika.PlainCredentials(username,password)
parameters = pika.ConnectionParameters("127.0.0.1","5672","vhost",credentials, heartbeat=0)
connection = pika.BlockingConnection(parameters)
channel = connection.channel()
return connection, channel
except:
return None, None
def BrokerListen():
def BrokerConnect():
while True:
try:
queue = "test-que"
connection, channel = BrokerConnection("admin", "123345")
if channel is not None:
brokerConnections.update({"key1":channel})
return connection, channel
except:
time.sleep(1)
print("error")
connection, channel, queue = BrokerConnect()
print(f'[*] Waiting for {queue} messages. To exit press CTRL+C')
def callback(ch, method, properties, body):
data = json.loads(body)
print(data)
ch.basic_ack(delivery_tag=method.delivery_tag)
channel.basic_consume(queue=queue, on_message_callback=callback)
channel.start_consuming()
def ConnectionClose():
channel = brokerConnections["key1"]
if channel.is_open:
connection = channel.connection
channel.stop_consuming()
connection.close()
del brokerConnections["key1"]
