I don`t know why this happened. The screen just show me these messages. After this I still try to edit my js file, it seems that just some of the tips can be used, not all. How can I make it work correctly? And if I need offer some more information?

No, it just won't work because there's a very specific problem in KubeJS's reflection helper which that I can fix with some handling, but I don't want to continue on the codebase anymore.

Is there anything that we as developers could do to work around it? Or even fix it?

Do you have any tips or strategies for diagnosing and debugging these exceptions. I happen to have encountered this issue myself.
