当从Log facade调用log方法时，它会将值为NULL的二进制数据重复写入laravel.log文件。
我尝试了几种调用Log facade的变体，结果都是一样的：

Log::channel('stack')->info("test");
        Log::channel("single")->info('test');
        Log::debug("test");

laravel.log文件中的输出显示在随附的屏幕截图中

我尝试注解掉logging.php文件中的所有通道，得到了相同的结果。
下面是logging.php文件的未注解版本

我不确定我们是否能解码。
我们正在使用Laravel 8运行supervisord
