Did some changes in the code and it works
StorageOptions options = StorageOptions.newBuilder()
.setProjectId(PROJECT_ID)
.setCredentials(GoogleCredentials.fromStream(new FileInputStream(PATH_TO_JSON_KEY))).build();
Storage storage = options.getService();
byte[] bytes = storage.readAllBytes(BlobId.of(BUCKET_NAME, OBJECT_NAME));
use storage.readAllBytes() instead of storage.get()
