What is this error and what's the solution?

This error occurs when a closure is used in a configuration file that is being cached. Closures cannot be serialized, so they cannot be cached. To fix this error, remove any closures from your configuration files or move them to a separate file that is not being cached.

Example:

// Bad configuration file with a closure
return [
    'key' => function () {
        return 'value';
    },
];

// Good configuration file without a closure
return [
    'key' => 'value',
];
