How to get response and request body in log file in GUNICORN?

Question

As of now, I am using a .conf file for logging in gunicorn.

My gunicorn.conf file looks like:

[loggers]
keys=root, gunicorn.error, gunicorn.access

[handlers]
keys=console, error_file, access_file

[formatters]
keys=generic, access

[logger_root]
level=INFO
handlers=console

[logger_gunicorn.error]
level=INFO
handlers=error_file
propagate=1
qualname=gunicorn.error

[logger_gunicorn.access]
level=INFO
handlers=access_file
propagate=0
qualname=gunicorn.access

[handler_console]
class=StreamHandler
formatter=generic
args=(sys.stdout, )

[handler_error_file]
class=logging.FileHandler
formatter=generic
args=('/var/log/gunicorn/gunicorn_error.log',)

[handler_access_file]
class=logging.FileHandler
formatter=access
args=('/var/log/gunicorn/gunicorn_access.log',)

[formatter_generic]
format={Time:[%(asctime)s], Process:[%(process)d], LogLevel:[%(levelname)s], Module:[%(module)s], Message:[%(message)s], PathName:[%(filename)s], ThreadId:[%(thread)d], ThreadName:[%(threadName)s]}
datefmt=%Y-%m-%d %H:%M:%S
class=logging.Formatter

[formatter_access]
format={Time:[%(asctime)s], Process:[%(process)d], LogLevel:[%(levelname)s], Module:[%(module)s], Message:[%(message)s], PathName:[%(filename)s], ThreadId:[%(thread)d], ThreadName:[%(threadName)s]}
class=logging.Formatter

I am running fastAPI wrapped around gunicorn.

Is there any way I can add request and response bodies in my access logfile?

I tried adding sys.stdout to the args parameter in handler_error_file, handler_access_file but that is throwing the error.
