TypeError: Cannot read properties of undefined (reading 'app') :'(
Question
I was investigating and I found a solution, it consisted of pasting these lines in the index.html
<script src = "https://www.gstatic.com/firebasejs/8.10.0/firebase-auth.js"> </script>
<script src = "https://www.gstatic.com/firebasejs/8.10.0/firebase-firestore.js"> </script>
<script src = "https://www.gstatic.com/firebasejs/8.10.0/firebase-storage.js"> </script>
but that did not solve my error, I don't know what can happen:/
