I am getting this error after the FitPro app installation:

Fatal error: Uncaught KreaitFirebaseExceptionInvalidArgumentException: A Service Account specification must have a field “type” with “service_account” as its value. Please make sure you download the Service Account JSON file from the Service Accounts tab in the Firebase Console, as shown in the documentation on https://firebase.google.com/docs/admin/setup#add_firebase_to_your_app in /home/u283267893/domains/morsacrm.com/public_html/app/classes/vendor/kreait/firebase-php/src/Firebase/ServiceAccount.php:112 Stack trace: #0

Can you help me identify what I should no, I have no experience with firebase apps

After installation I expected to see the login page
