Schema 🍥

Bugs 🐞 🪲

  • In home page, we first placed the following line outside the if...else statement:
response.send(layoutHTML('Home', homeHtml));

As a result the home page was not rendering even when the user was successfully logged in.

💡 To solve this: We moved this line once in the if statement and once in the else.
