Directory[TOC]First, the problem is thrownPython's logging module is a powerful tool for Python to print logs during use. We can use the logger, Handler, formatter of the logging module to encapsulate our logs, specifying the path, format, and location of the log output. When declaring logger, you can pass a string as a label for this logger. Always thought that

I have several projects that use Sentry to capture the ERROR level of the log and now have a problem: when debugging locally, all handler (including root) in the log settings are only hit on the console, but exceptions that are not caught in local debugging will hit the line sentry Above, and the caught exception follows my log settings and only hits the console. I wonder if the uncaught exception is not the root handler of the walk?My solution is to read through the
