JavaScript Array Iteration Methods exercise....buggy?

I submitted my answer for a coding challenge (https://teamtreehouse.com/library/javascript-array-iteration-methods/combining-array-methods/combining-filter-and-map). I keep getting error " Line 24: Unexpected token ILLEGAL" but if I execute the code with node.js it passes with no error. Any hint is appreciated!

Here's my code: 

const todos = [
    {
        todo: 'Buy apples',
        done: false
    },
    {
        todo: 'Wash car',
        done: true
    },
    {
        todo: 'Write web app',
        done: false
    },
    {
        todo: 'Read MDN page on JavaScript arrays',
        done: true
    },
    {
        todo: 'Call mom',
        done: false
    }
];
let unfinishedTasks;
unfinishedTasks = todos
.filter(todo => todo.done == false)
.map(todo => (`${todo.todo}`))

Hey Gael,

Here is a "hint" as requested:

The todo.todo is already a string. 🤔

Sounds like it's just a subtle discrepancy in how Treehouse interprets vs Node

You could try just rearranging the bottom few lines of code a bit. Maybe this will work:

let unfinishedTasks = todos
    .filter( todo => todo.done == false )
    .map( todo => (`${todo.todo}`) );
