Firestore Null Pointer Exception on firestoreoptions.getService

Hi i am using SmartFoxServer with a Java extension. Inside that extension i am trying to get firestore instance. Below is the code i am using to connect to service that is working fine inside IDE (Eclipse). but when i deploy my extension on SmartFoxServer it gives a null pointer exception on firestoreOptions.getService

String jsonPath = "data/************.json";
        GoogleCredentials credentials = null;
            try {
                credentials = GoogleCredentials.fromStream(new FileInputStream(jsonPath))
                        .createScoped(Lists.newArrayList("https://www.googleapis.com/auth/cloud-platform"));
            } catch (FileNotFoundException e1) {
                trace("Exception" + e1.toString());
            } catch (IOException e1) {
                trace("Exception" + e1.toString());
            }

            FirestoreOptions firestoreOptions = FirestoreOptions.newBuilder().setCredentials(credentials).build();

            Firestore db = firestoreOptions.getService();
            this.db = db;
            try {
                run();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                trace("Exception : " + e);
            }

Here is the exception i am getting.

    com.google.cloud.firestore.FirestoreException:

i am new to firestore. Don't know if any jar file/library is missing to run this code on server. any help would be appreciated.

GOOGLE_APPLICATION_CREDENTIALS

environment variable must be added with the correct credential's file path and name to run firestore on server.
