Getting pika.exceptions.StreamLostError: Transport indicated EOF while running python script docker image which using pika

I am using Python which is using RabbitMQ for input and output. I am able to run my script locally without any errors but when I try to Dockerize that script and run it it’s giving me the following error:

Traceback (most recent call last):
File "./Kusto_connection_with_rabbitmq_2.py", line 1674, in <module>

 pika.exceptions.StreamLostError: Transport indicated EOF

Below is the my Python code which is connecting to RabbitMQ:

credentials = pika.PlainCredentials(username, password)
parameters = pika.ConnectionParameters(host=Api_url,virtual_host=rmqvhost,credentials=credentials,heartbeat=0)
print (username,password)
connection = pika.BlockingConnection(parameters)
channel = connection.channel()

channel.queue_declare(queue='test',durable=True)


channel.basic_qos(prefetch_size=0,prefetch_count=1) # this is for acknowdeging packet one by one 
channel.basic_consume(queue='test', on_message_callback=callback,auto_ack=False)


print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()

My Dockerfile:

FROM python:3.8
WORKDIR /First_try
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY Kusto_connection_with_rabbitmq_2.py .
CMD ["python","./Kusto_connection_with_rabbitmq_2.py"]

I run my Docker container with

docker run <image_name>
