code :

import inquirer from 'inquirer';

const choices = Array.apply(0, new Array(26)).map((_: any, y: any) => String.fromCharCode(y + 65));
inquirer
  .prompt([
    {
      type: 'list',
      loop: false,
      name: 'letter',
      message: "What's your favorite letter?",
      choices,
    },
    {
      type: 'checkbox',
      name: 'name',
      message: 'Select the letter contained in your name:',
      choices,
    },
  ])
  .then((answers: any) => {
    console.log(JSON.stringify(answers, null, '  '));
  });

I can confirm the bug. Seems to be a regression in 8.2.3. Downgrading to 8.2.2 works for me.

Can confirm, this is happening since 8.2.3. Downgrade to 8.2.2 fixes it for me

Hey @starpit, I was wondering if there was any chance you could look into this? It seems to occur starting with the ansi-wrap change 😓

The bug seems to be that breakLines is expected, by the paginator, to return a doubly-nested array, where the inner array are the lines into which a line might be broken.

The main screen manager does not rely on this aspect.

I'll send a PR.
