I couldn't find a working Telegraf inline query project – Telegram API

I want to make a telegram bot about algebra. I need to send code to http://api.mathjs.org/v4/?expr=2*(7-3) after the expr part. I want to send numbers with inline query, but how can I do it?

    You can find multiple examples of Telegraf usage at https://github.com/telegraf/telegraf/tree/develop/docs/examples

    Here is an example of a bot utilizing an inline query

    The original example uses context object deconstruction, which doesn’t seem to work and spits out error:

    TypeError: Cannot read property 'assert' of undefined

    Here is the code without object deconstruction, which works for me (I’ve made it superfluously verbose for better understanding ):

    bot.on('inline_query', async (ctx) => {


  const offset = parseInt(ctx.inlineQuery.offset) || 0;

  let items = [];

  for(var i = 0; i < 100; i++) {
    items.push({ title: 'Item '+i, desc: 'item '+i+' desc', id: '0000'+i, moreinfo: 'More info about item'+i+', mucho importante information'})
  }

  let results = items.slice(offset, offset+10).map((item) => ({
    type: "article",
    id: item.id,
    title: item.title,
    description: item.desc,
    input_message_content: {
      message_text: '*'+item.title+'*n'+item.desc,
      parse_mode: 'Markdown'
    },
    reply_markup: {
        inline_keyboard: [
          [{ text: 'More info', callback_data: 'moreinfo' }]
    ]},
    hide_url: true,
    url: 'http://www.domain.se/'+item.id,
  }));

  console.log('hello');

  let ourReturn = ctx.answerInlineQuery(results, {is_personal: true, next_offset: offset+results.length, cache_time: 10});

  return ourReturn;
});

    Here is the article that helped me to solve this problem.
