The security token included in the request is expired, when I try to update credentials

[dariusjvc]

I am using Celery with SQS as a broker and I am trying to renew my credentials "AWS_ACCESS_KEY_ID" and "AWS_SECRET_ACCESS_KEY", before they expire, the first time I run the task and the result is success, but after 15 minutes it expires although credentials have been renewed, the function to update credentials is as follows:

import os
import boto3

from celery import Celery
from kombu.utils.url import safequote

def update_aws_credentials():
  role_info = {
            'RoleArn': f"arn:aws:iam::{os.environ['AWS_ACCOUNT_NUMER']}:role/my_role_execution",
            'RoleSessionName': 'roleExecution',
            'DurationSeconds': 900
        }
  sts_client = boto3.client('sts', region_name='eu-central-1')
  credentials = sts_client.assume_role(**role_info)

  aws_access_key_id = credentials["Credentials"]['AccessKeyId']
  aws_secret_access_key = credentials["Credentials"]['SecretAccessKey']
  aws_session_token = credentials["Credentials"]["SessionToken"]

  os.environ["AWS_ACCESS_KEY_ID"] = aws_access_key_id
  os.environ["AWS_SECRET_ACCESS_KEY"] = aws_secret_access_key
  os.environ["AWS_DEFAULT_REGION"] = 'eu-central-1'
  os.environ["AWS_SESSION_TOKEN"] = aws_session_token

  return aws_access_key_id, aws_secret_access_key

def get_celery(aws_access_key_id, aws_secret_access_key):
  broker = f"sqs://{safequote(aws_access_key_id)}:{safequote(aws_secret_access_key)}@"
  backend = 'redis://redis-service:6379/0'
  celery = Celery(f"my_task", broker=broker, backend=backend)
  celery.conf["broker_transport_options"] = {
      'polling_interval': 30,
      'region': 'eu-central-1',
      'predefined_queues': {
      f"my_queue": {
              'url': f"https://sqs.eu-central-1.amazonaws.com/{os.environ['AWS_ACCOUNT_NUMER']}/my_queue"
          }
      }
  }
  celery.conf["task_default_queue"] = f"my_queue"
  return celery

def refresh_sqs_credentials():
  access, secret = update_aws_credentials()
  return get_celery(access, secret)

Running refresh_sqs_credentials, new credentials are created:

celery = worker.refresh_sqs_credentials()

And then I run my task with celery:

task = celery.send_task('my_task.code_of_my_task', args=[content], task_id=task_id)

All tasks that I run before 15 minutes finish successfully, but after 15 minutes the error is the following:
