Hello,
I’m struggling with this part of the lab. I’ve debugged it with each of the authors in the console and the code returns an array with the correct books, as asked. Can anyone point me in the right direction please?

const library = [
  {
    title: 'Your Next Five Moves: Master the Art of Business Strategy',

  },

    pages: 320,
  },

    author: 'Patrick Bet-David',
    about:
      "A book that emphasizes the importance of identifying and understanding one's adversaries to succeed in the business world",
    pages: 304,
  },
  {
    title: 'The Embedded Entrepreneur',
    author: 'Arvid Kahl',
    about: 'A book focusing on how to build an audience-driven business',
    pages: 308,
  },
  {

    author: 'Jon Gordon',
    about: 'A book about effective ways to lead a coffee bean lifestyle',
    pages: 256,
  },
  {
    title: 'The Creative Mindset: Mastering the Six Skills That Empower Innovation',
    author: 'Jeff DeGraff and Staney DeGraff',
    about: 'A book on how to develop creativity and  innovation skills',
    pages: 168,
  },
  {
    title: 'Rich Dad Poor Dad',
    author: 'Robert Kiyosaki and Sharon Lechter',
    about: 'A book about financial literacy, financial independence, and building wealth. ',
    pages: 336,
  },
  {
    title: 'Zero to Sold',
    author: 'Arvid Kahl',
    about: 'A book on how to bootstrap a business',
    pages: 500,
  },
];

function displayBooks(catalog) {
  let output = 'Books in the Library:\n';

  catalog.forEach((book) => {
    output += `- ${book.title} by ${book.author} (${book.pages} pages)\n`;
  });

  return output;
}

function getBookSummaries(catalog) {
  return catalog.map((book) => book.about);
}


function getBooksByAuthor (catalog, author){
  let output = [];
  output.push(catalog.filter((catalog)=> catalog.author.includes(author)));
  return output.flat(); 
}

you should not return also the books where the author is present in a group of authors

like, if the search is for Jeff DeGraff, you should not get the book where the autor is author: 'Jeff DeGraff and Staney DeGraff',
