Solution to thinkphp 5 error display nginx 404 page

[ sql ] [ SQL ] SELECT `data_id`,`pid` FROM `tb_data_manage` WHERE  `pid` IN (53,49,47,46,35) [ RunTime:0.000595s ]
[ error ] [8]未定义数组索引: see[/data/web/data_manage/runtime/temp/5e9fc553d7acc7eaa186b674b2a29538.php:143]

Obviously, it is PHP that has an error, not nginx that cannot find the page, and nginx's pathinfo There is no problem with the settings. I also set app_debug in config.php to true, so I searched for solutions online. The final solution was to open the file think_exception.tpl under thinkphp/tpl at the end of the php file. Add an exit

        })();
    </script>
    <?php } exit; ?>
</body>
</html>

to the tag and the problem will be solved. If you access the browser again, 404 will no longer be displayed and the thinkphp error page will appear.
