Hi.

I guess you have two configured handlers: the first one logs messages to sys.stderr (this is the default handler automatically added), the second one logs messages to "protectwise_bootstrap.log" (the handler you manually added).

The backtrace properties of handlers are independent of each others. The default handler use backtrace=True. So, even if you add a new handler with logger.add(..., backtrace=False), the default one is not modified and will display full traceback.

You can either set LOGURU_BACKTRACE=NO for development, or explicitly add a sys.stderr handler with backtrace=False:

logger.remove()  # Remove default handler (and all others)
logger.add(sys.stderr, backtrace=False)
logger.add("protectwise_bootstrap.log", backtrace=False, format="{time:YYYY-MM-DD at HH:mm:ss} | {level} | {message}")

Alternatively, using configure():

# Default handler (and all others) is automatically removed while using '.configure()'
logger.configure(handlers=[
    {"sink": sys.stderr, "backtrace": False},
    {"sink": "protectwise_bootstrap.log", "backtrace": False, "format": "{time:YYYY-MM-DD at HH:mm:ss} | {level} | {message}"}
])
