I have created app using prototyper. When I initially created it, everything was working fine. But when I am opening that same app now in prototyper, I’m getting blank screen. When i checked the console by clicking inspect im getting following error

index-CFSvYrbX.js:41 Uncaught TypeError: Cannot read properties of undefined (reading ‘firestore’)
