Anyone know why I keep on getting "Bummer: Cannot read property '1' of null"?

Not sure what i'm doing wrong here

app.js 
// Complete the challenge by writing JavaScript below
const button = document.getElementById('btn-Phrase')

button.addEventListener('click', () => {
  alert(input.value);
});
index.html 
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Phrase Sayer</title>
  </head>
  <body>
    <p><label for="input-phrase">Type a phrase</label></p>
    <p><input type="text" id="input-phrase"></p>
    <p><button id="btn-phrase">Say Phrase</button></p>
    <script src="app.js"></script>
  </body>
</html>

It's because of the capital 'P' in your getElementById method parameter. Change btn-Phrase to btn-phrase
