Disable HTTP logs in apps platform

I have a flask application running in gunicorn in the app platform. Run command:

gunicorn --config gconfig.py --worker-tmp-dir /dev/shm --log-level error wsgi:app

gconfig.py:

bind = '0.0.0.0:8080'
workers = 2
worker_class = 'gevent'
worker_connections = 1000

flask init:

if logging.getLogger('gunicorn.error').handlers:
    app.logger.handlers.clear()
    app.logger.handlers.extend(
        logging.getLogger('gunicorn.error').handlers)
    app.logger.setLevel(logging.INFO)

But the logs contain http requests:

app-name | 2021-02-18 19:28:13 10.244.8.44 - - [18/Feb/2021:17:28:13 +0000] "POST /route HTTP/1.1" 200 322 "-" "Apache-HttpClient/4.5.7 (Java/1.8.0_212)"

I want the logs to contain only errors and the messages that I send myself:

current_app.logger.info('some log message')
