问题

I'm getting an error when trying to detect the click of a form button using GeyserMC's API. This is what it says:
在尝试使用GeyserMC的API检测表单按钮点击时，我遇到了一个错误。错误信息如下：
Inconvertible types; cannot cast '' to 'org.geysermc.cumulus.response.SimpleFormResponse'
不可转换的类型；无法将''转换为'org.geysermc.cumulus.response.SimpleFormResponse'

This is what i did/tried which is giving that error:

  4. **得分**: 0
  5. 我认为这一行`SimpleFormResponse response = (SimpleFormResponse) responseData;`可能是导致问题的原因。
  6. 在查看文档后，您设置`ResponseHandler`的方式已被弃用：https://github.com/GeyserMC/Cumulus/wiki/Updating-from-1.0-to-1.1-(and-2.0)#response-handling-changes
  7. 弃用的方式可能仍然被实现，但您使用的Lambda函数只返回一个字符串（可能是`responseData`），而不是两个（`formPlayer, responseData`）：https://github.com/GeyserMC/Cumulus/blob/master/src/main/java/org/geysermc/cumulus/Form.java

  10. I don&#39;t know which Version you are using, so I am guessing the newest.
  11. I think the line `SimpleFormResponse response = (SimpleFormResponse) responseData;` is causing the problem. 
  12. After looking into the documentation, the way you are setting the `ResponseHandler` is deprecated: https://github.com/GeyserMC/Cumulus/wiki/Updating-from-1.0-to-1.1-(and-2.0)#response-handling-changes
  13. The deprecated way may still be implemented, but the lambda function you are using is only returning one String (probably `responseData`) and not two (`formPlayer, responseData`): https://github.com/GeyserMC/Cumulus/blob/master/src/main/java/org/geysermc/cumulus/Form.java
