But how to throw an error in a lifecycle hook…?

async beforeUpdate(event) {
  if (condition) {
    // Throw an error here
  }
},

We have no access to a ctx like in the controllers:

I would like to show something like this (with a custom message if possible):

Any news regarding this issue? I’m having the same problem. I would like to return a 400 error and show a friendly message instead of a 500 error.

I got to do it doing this:

const { ForbiddenError } = require("@strapi/utils").errors;

...

if (!authorized) {
  throw new ForbiddenError(errorMessage);
}

You can check the errors available in @strapi/utils/lib/errors.js
