Lifecycle error doesnt appear in UI, only as internal error

Throw Error message in lifecycle hook doesnt change the error message display in the UI

Strapi Version: 3.3.4 Operating System: macOS Database: SQLlite Node Version: 12.18 NPM Version: Yarn Version:

Hi, I was trying to add some custom validation logic in the “beforeCreate” lifecycle hook, but I was not able to customize the error message displayed in the UI , it is always returning the default one. I tried to throw a “new Error”(“custom message”)" but no luck there. Is it something doable ? B.R

there is a similar discussion, but it doesnt work for me.

When i create error as it is written in docs:

const { errors } = require("@strapi/utils");
const { ApplicationError } = errors;
...
async beforeCreate(event) {
    let okay = false;

    // Throwing an error will prevent the entity from being created
    if (!okay) {
      throw new ApplicationError("Something went wrong", 400);
    }
}

it is in the browser console, but doesnt show up in admin ui. my goal is to create custom validation in lifecycle in cases when it is not possible through admin page. then i want to show custom error to user in ui, so he would know why he cant save changes

4.15.0: Application Error is returning Internal Server Error instead of actual error.

there is a fresh issue on github that resolved my problem.

i needed to upgrade my strapi packages versions from 4.20.3 to 4.20.4
