注意：未定义索引：args

Question

我使用Bolt CMS（+Docker-nginx，PHP 7.4 FPM）进行工作。 我遇到了以下错误。

在/var/www/vendor/bolt/bolt/src/EventListener/ExceptionListener.php的第285行中的ContextErrorException：注意：未定义索引：args

导致错误的行是以下行。

$trace[$key]['args_safe'] = $this->getSafeArguments($trace[$key]['args']);

$trace是从以下行开始初始化的。

$trace = $exception->getTrace();

default.conf文件的内容如下。

server {
    server_name                   localhost;
    client_max_body_size 10M;

    # Site root
    root                          /var/www/public;

    location / {
        try_files                     $uri $uri/ /index.php?$query_string;
    }

    # Bolt dashboard and backend access
    #
    # We use two location blocks here. The first is an exact match to the dashboard and
    # the next is a strict forward match for URIs under the dashboard. This in turn
    # ensures that the exact branding prefix has absolute priority, and that
    # restrictions that contain the branding string, e.g. "bolt.db", still apply.
    #
    # NOTE: If you set a custom branding path, change '/bolt' & '/bolt/' to match
    location = /bolt {

    }

    # Apache .htaccess & .htpasswd files
    location ~ /\.(htaccess|htpasswd)$ {
        deny                          all;
    }

    # Block access to SQLite database files
    location ~ /\.(?:db)$ {

    }

    # Block access to Markdown, Twig & YAML files directly
    location ~* /(.*)\.(?:markdown|md|twig|yaml|yml)$ {
        deny                          all;
    }
}

当我将$trace[$key]['args_safe'] = $this->getSafeArguments($trace[$key]['args']);更改为$trace[$key]['args_safe'] = '';时，它可以工作，但我不想更改外部库中的文件。问题出在哪里？

我遇到了相同的错误。

解决方法：

将您的PHP版本更改为较旧的版本。在7.2上可以运行。
