Cannot read properties of undefined (reading ‘length’)

The issue might occur due to the conflict with the other plugins. Can you please check once by deactivating the plugins on your site one by one and let us know back which plugin is causing the issue?

I disabled most of the plugins that are not required from the theme and for the work of the site but still errors:

Uncaught TypeError: firebase.apps is undefined
<anonymous> https://svetlio.rocks/pwa-register-sw.js?ver=1.7.41:9
pwa-register-sw.js:9:7
<anonymous> https://svetlio.rocks/pwa-register-sw.js?ver=1.7.41:9
Uncaught TypeError: firebase.apps is undefined
<anonymous> https://svetlio.rocks/wp-content/plugins/pwa-for-wp/assets/js/pwa-push-notification.js?ver=1.7.41:10

i will try in the morning to disable all of them but i am not sure that it will help
