Tell us about the problem

My angular - Nativescript project uses the Nativescript-Firebase-Plugin. It works perfectly well in Nativescript 3.3.0 I upgraded my project to Nativescript 3.4.0. After upgrading the project, I am facing a major issue with all firebase queries on Android.

**JS: Error in firebase.query: TypeError: Cannot read property 'child' of null** JS: NO QUESTIONS FOR THIS USER JS: ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'length' of undefined JS: TypeError: Cannot read property 'length' of undefined JS: at file:///data/data/org.nativescript.qbank/files/app/feed/alphaCreate.component.js:55:23 JS: at SafeSubscriber.schedulerFn [as _next] (file:///data/data/org.nativescript.qbank/files/app/tns_modules/@angular/core/bundles/core.umd.js:3870:36) JS: at SafeSubscriber.__tryOrUnsub (file:///data/data/org.nativescript.qbank/files/app/tns_modules/rxjs/Subscriber.js:238:16) JS: at SafeSubscriber.next (file:///data/data/org.nativescript.qbank/files/app/tns_modules/rxjs/Subscriber.js:185:22) JS: at Subscriber._next (file:///data/data/org.nativescript.qbank/files/app/tns_modules/rxjs/Subscriber.js:125:26) JS: at Subscriber.next (file:///data/data/org.nativescript.qbank/files/app/tns_modules/rxjs/Subscriber.js:89:18) JS: at EventEmitter.Subject.next (file:///data/data/org.nativescript.qbank/files/app/tns_modules/rxjs/Subject.js:55:25) JS: at EventEmitter.emit (file:///data/data/org.nativescript.qbank/files/app/tns_modules/@angular/core/bundles/core.umd.js:3844:76) JS: at file:///data/data/org.nativescript.qbank/files/app/services/my-questions.service.js:51:42 JS: at ZoneDelegate.invoke (file:///data/data/org.nativescript.qbank/files/app/tns_modules/nativescript-angular/zone-js/dist/zone-nativescript.js:365:26) JS: at Object.onInvoke (file:///data/data/org.nativescript.qbank/files/app/tns_modules/@angular/core/bundles/core.umd.js:4156:37) JS: at ZoneDelegate.invoke (file:///data/data/org.nativescript.qbank/files/app/tns_modules/nativescript-angular/zone-js/dist/zone-nativescript.js:364:32) JS: at Zone.run (file:///data/data/org.nativescript.qbank/files/app/tns_modules/nativescript-angular/zone-js/dist/zone-nativescript.js:125:43) JS: at file:///data/data/org.nativescript.qbank/files/app/tns_modules/nativescript-angular/zone-js/dist/zone-nativescript.js:760:57 JS: at ZoneDelegate.invokeTask (file:///data/data/org.nativescript.qbank/files/app/tns_modules/nativescript-angular/zone-js/dist/zone-nativescript.js:398:31)

I tried to resolve it by
a. upgrading the native script firebase plugin: 5.0.5
b. upgrading all the dependenices of the project

But the issue is still occurring. This is a big blocker, and Please suggest what I can do to fix this.
