火星AI 插件报错：TypeError: Cannot read properties of undefined (reading 'fnc')

The error message 'TypeError: Cannot read properties of undefined (reading 'fnc')' suggests an issue with the plugin's configuration or implementation. Specifically, the 'fnc' property seems to be undefined, causing the error.

To troubleshoot this, follow these steps:

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

If the problem persists, provide more information or debug the code further to pinpoint the cause of the error.
