azure web app loaded from github repo based on spring boot problem - azure-web-app-service

Question

yesterday i linked my github to an azure web app service
my repo built with rest requests and some of them is working with loading data from firestore based databased , i ran it all on localhost on the tomcat embedded server that comes with spring
,got the web app in the air and my post request which getting resource from firebase , the post request got me an internal 500 server so i check the app insights feature to check what exception i get
java.lang.IllegalStateException: FirebaseApp with name [DEFAULT] doesn't exist.
at com.google.firebase.FirebaseApp.getInstance(FirebaseApp.java:165)
at com.google.firebase.FirebaseApp.getInstance(FirebaseApp.java:136)
my init code for fire base is:
package Model;
import com.google.auth.oauth2.GoogleCredentials;
import com.google.firebase.FirebaseApp;
import com.google.firebase.FirebaseOptions;
import org.springframework.stereotype.Service;
import javax.annotation.PostConstruct;
import java.io.File;
import java.io.FileInputStream;
import java.util.Objects;
#Service
public class FBInitialize {
#PostConstruct
public void initialize() {
try {
String fileName = "name of json file with Credential.json";
ClassLoader classLoader = getClass().getClassLoader();
File file = new File(Objects.requireNonNull(classLoader.getResource(fileName)).getFile());
FileInputStream serviceAccount = new FileInputStream(file);
FirebaseOptions options = new FirebaseOptions.Builder()
.setCredentials(GoogleCredentials.fromStream(serviceAccount))
.setDatabaseUrl("https://qr-database-my data base url")
.build();
FirebaseApp.initializeApp(options);
} catch (Exception e) {
e.printStackTrace();
}
}
i checked on the logs and i did got the request i just getting this exception is anyone ever encounter
this exception ?
by the way on initiazlizeApp method the getIntstance methood is being called.
Edit:
found where the exception was thrown from :
public static FirebaseApp getInstance(#NonNull String name) {
synchronized(appsLock) {
FirebaseApp firebaseApp = (FirebaseApp)instances.get(normalize(name));
if (firebaseApp != null) {
return firebaseApp;
} else {
List<String> availableAppNames = getAllAppNames();
String availableAppNamesMessage;
if (availableAppNames.isEmpty()) {
availableAppNamesMessage = "";
} else {
availableAppNamesMessage = "Available app names: " + Joiner.on(", ").join(availableAppNames);
}
String errorMessage = String.format("FirebaseApp with name %s doesn't exist. %s", name, availableAppNamesMessage);
throw new IllegalStateException(errorMessage);
}
}
}

The problem may be the source code version on github. Please check build.gradle file under android/app folder.
Add the following line:
apply plugin:'com.google.gms.google-services'

im working with maven , also i figured it out that its has something with the json file with the google credentials location because repackaging the file changing the root content to BOOT-INF so i took the json file content put it in a String and cast it to Inputstream so the Initializeapp and the init would be independent but it still no joy :(
new update:
now i get a different exception I think its about security
java.lang.IllegalStateException: Could not find TLS ALPN provider; no working netty-tcnative, Conscrypt, or Jetty NPN/ALPN available
agian im working with maven and not on android
