Error occurred while adding a new consumer - rabbitmq

I am getting following error when I am trying to add a new consumer(queue) from the current_app imported from celery by issuing the control command.
The details of logged error are as follows:
reply = current_app.control.add_consumer(queue_name, destination = WORKER_PROCESSES, reply = True)

I didn't understand the error. I am passing a queue name different from the one mentioned in logs.
Any help will be appreciated. Thanks.
Note: This issue starts occurring after setting MAX_TASK_PER_CHILD value. Is this related to the error ?

Why am I getting a 503 from the Amedeus airport API?

I am using the Amadeus Python 3 client, and I get a 503 when calling the method `
response = amadeus.reference_data.locations.airports.get(
longitude=long,
latitude=lat)
`
Stack trace: `

`
Is the API down at the moment?
a 503 is a server error. If the api has a status page, check that. If not, reach out to whoever runs it if that is known. Other than that, only those with access to the servers can tell you why.

The first time I touched Telethon, I changed the api_id and api_hash, and then ran the program, but the following error was reported:

May I ask what modifications I need to make to run this program(https://github.com/edogab33/telegram-groups-crawler)? Do I need a Telegram group file? Can you provide a simple example? Thank you.

I have confirmed that my S3 file is accessible from my local ubuntu machine however does not work on aws
This seems to be related to an open issue open issue on Zappa
I had the same issue my Zappa deployment,
I tried all possible options but nothing was working, But after trying different suggestions the following steps worked for me
I copied python3.8/site-packages/botocore/cacert.pem to my lambda folder
I Set the "REQUESTS_CA_BUNDLE" environment variable to /var/task/cacert.pem
/var/task is where AWS Lambda extracts your zipped up code to.
How to set environment variables in Zappa
I updated my Zappa function and everything worked fine
fixed this by adding the cert path to environment (python)
os.environ['REQUESTS_CA_BUNDLE'] = os.path.join('/etc/ssl/certs/','ca-certificates.crt')
Edit: Sorry the issue was not really fixed with the above code, but found a hack work around by adding verify=False for all ssl requests
boto3.client('s3', verify=False)

Error accessing AWS elasticache redis in cluster mode) + TLS Enabled from django service

I'm trying to connect AWS elasticache(redis in cluster mode) with TLS enabled, the library versions and django cache settings as below
====Dependencies======
redis==3.0.0
redis-py-cluster==2.0.0
django-redis==4.11.0
======settings=======
CACHES = {
'default': {
'BACKEND': 'django_redis.cache.RedisCache',

'CONNECTION_POOL_KWARGS': {
'skip_full_coverage_check': True,
"ssl_cert_reqs": False,
"ssl": True
}
}
}
}
It doesn't seem to be a problem with client-class(provided by redis-py-cluster) since I'm able to access
from rediscluster import RedisCluster
startup_nodes = [{"host": "redis://xxxxxxx.mc-redis-cache-v2.zzzzz.usw2.cache.amazonaws.com", "port": "6379"}]
rc = RedisCluster(startup_nodes=startup_nodes, ssl=True, ssl_cert_reqs=False, decode_responses=True, skip_full_coverage_check=True, password='<password>')
rc.set("foo", "bar")
rc.get('foo')
'bar'
but I'm seeing this error when django service is trying to access the cache, is there any configuration detail that I might be missing?

I also tried passing "ssl_ca_certs": "/etc/ssl/certs/ca-certificates.crt" to CONNECTION_POOL_KWARGS and setting the location scheme to rediss still no luck
you need to change ssl_cert_reqs=False to ssl_cert_reqs=None

telepot.exception.TelegramError: ('Bad Request: wrong HTTP URL specified', 400, {'ok': False, 'error_code': 400, 'description': 'Bad Request: wrong HTTP URL specified'})
the same happened with sendPhoto, but I used python requests to send photos
response =requests.post('https://api.telegram.org/bot/sendphoto', files=files`)
I either want to know why the sendAudio() and sendPhoto() methods work or the http url to send audio
with telepot bot.SendPhoto and bot.sendVideo and bot.sendAudio work either with files and urls that contains a file.
In your case it seems that you used and url and it was uncorrect, can you share it?
In my experience it can be because the url contains & instead of &
