Thank for your feedback sir.

i have been trying to fix an old code which still use Javalin 4.x.x and have to update to 6.x.x, yet still use some outdated API as below so it didn't work.

    config.plugins.enableDevLogging(); // Approach 1

I am new to code, I wonder how did you update yourself with the Javalin docs? I have been searching but haven't been able to solve the problem until I came across your posts.
