Type Handler Issue in MyBatis of Spring Boot
showing a couple hundred lines of code and a stack trace isn't exactly an MRE, especially when it comes to Spring. Try and narrow down what is actually causing the issue

recursion
if you don't understand recursion, I would try to visualize the call stack of a java program. When you call methods inside methods, the context of the original method is saved in a stack data structure. When a recently called method returns, it's popped off the stack. There is nothing special about recursion, it's just calling a method and that method call happens to be in the same method called.

How can i run some dom manip before rendering?
basically I have a localStorage value that determines if the site will be dark or light themed, but for some reason this code runs after it has already rendered leading to a flickering effect.

// @refresh reload

import { mount, StartClient } from "@solidjs/start/client";
const theme = JSON.parse(localStorage.getItem("theme")!!)
if (theme) {
  document.body.classList.add("dark")
} else {
  document.body.classList.remove("dark")
}
mount(() => <StartClient />, document.getElementById("app")!);
