Thanks!
I had to see the code to override it correctly [1]
--------------------
class LoggerAdapter_(logging.LoggerAdapter):
def __init__(self, logger, extra):
self.logger = logger
self.extra = extra
def process(self, msg, kwargs):
kwargs["extra"] = self.extra
return "message->" + msg.upper(), kwargs
