The error message suggests that there is an issue with the plugin's configuration or implementation. Specifically, it seems that the 'fnc' property is undefined, which is causing the error.

To troubleshoot this issue, you can try the following steps:

1. Check the plugin's code and ensure that the 'fnc' property is properly defined in the 'rule' array.
2. Verify that the regular expression in the 'reg' property of the rule is correct and matches the intended pattern.
3. Make sure that the 'sendMessageToMarsAI' method is defined and accessible within the ExamplePlugin class.
4. Confirm that the plugin is being loaded correctly and included in the bot's configuration.

If the issue persists, you may need to provide more information or debug the code further to identify the exact cause of the error
