Not obtaining correct function call in the logs due to @logger.catch(reraise=True)

[LaxmanSinghTomar]

Hello, first of all, thanks for the great package. I've been using @logger.catch(reraise=True) wherever I've put a try/exception block. This is my logging_config.json:

{
  "logger": {
    "filename": "logs/access.log",
    "level": "info",
    "rotation": "20 days",
    "retention": "1 months",
    "format": "<level>{level: <8}</level> <green>{time:YYYY-MM-DD HH:mm:ss.SSS}</green> request id: {extra[request_id]} - <cyan>{name}</cyan>:<cyan>{function}</cyan> - <level>{message}</level>"
  }
}

and following is my custom_logger.py file:

import json
import logging
import sys
from pathlib import Path

from loguru import logger

LOGS_DIR = Path("logs")

# Create Directories
LOGS_DIR.mkdir(parents=True, exist_ok=True)


class InterceptHandler(logging.Handler):
    loglevel_mapping = {
        50: "CRITICAL",
        40: "ERROR",
        30: "WARNING",
        20: "INFO",
        10: "DEBUG",
        0: "NOTSET",
    }

    def emit(self, record):
        try:
            level = logger.level(record.levelname).name
        except AttributeError:
            level = self.loglevel_mapping[record.levelno]

        frame, depth = logging.currentframe(), 2
        while frame.f_code.co_filename == logging.__file__:
            frame = frame.f_back
            depth += 1

        log = logger.bind(request_id="app")
        log.opt(depth=depth, exception=record.exc_info).log(level, record.getMessage())


class CustomizeLogger:
    @classmethod
    def make_logger(cls, config_path: Path):

        config = cls.load_logging_config(config_path)
        logging_config = config.get("logger")

        logger = cls.customize_logging(
            logging_config.get("filename"),
            level=logging_config.get("level"),
            retention=logging_config.get("retention"),
            rotation=logging_config.get("rotation"),
            format=logging_config.get("format"),
        )
        return logger

    @classmethod
    def customize_logging(cls, filepath: Path, level: str, rotation: str, retention: str, format: str):

        logger.remove()
        logger.add(sys.stdout, enqueue=True, backtrace=True, level=level.upper(), format=format)
        logger.add(
            str(filepath),
            rotation=rotation,
            retention=retention,
            enqueue=True,
            backtrace=True,
            level=level.upper(),
            format=format,
        )
        logging.basicConfig(handlers=[InterceptHandler()], level=0)
        logging.getLogger("uvicorn.access").handlers = [InterceptHandler()]
        for _log in ["uvicorn", "uvicorn.error", "fastapi"]:
            _logger = logging.getLogger(_log)
            _logger.handlers = [InterceptHandler()]
        for _log in ["posthog", "posthog.error", "backoff"]:
            _logger = logging.getLogger(_log)
            _logger.handlers = [InterceptHandler()]
            _logger.setLevel = 50

        return logger.bind(request_id=None, method=None)

    @classmethod
    def load_logging_config(cls, config_path):
        config = None
        with open(config_path) as config_file:
            config = json.load(config_file)
        return config

The logs that are generated are shown below:

INFO     2022-09-07 11:39:41.042 request id: None - app.api:index_chunked_files - ✅ Received valid input: toxic_utils.py : text/x-python
WARNING  2022-09-07 11:39:41.049 request id: None - loguru._logger:catch_wrapper - text/x-python is not supported
ERROR    2022-09-07 11:39:41.052 request id: None - loguru._logger:catch_wrapper - An error has been caught in function 'catch_wrapper', process 'SpawnProcess-1' (7), thread 'MainThread' (140477093877568):

Instead of loguru._logger:catch_wrapper, how can I obtain the exact function where this exception was triggered similar to the first line showing app.api:index_chunked_files?

Hi @LaxmanSinghTomar. Sorry but I'm unable to reproduce your problem. Are you able to provide a minimal reproducible example please, that would help me investigate the issue.
