FirebaseStorageException. Failed to save image in firebase storage

Question

I am trying to capture an image via camera and save it to Firebase Storage (along with some text data). The text data is stored successfully in the Firebase Database. However upon saving the image in Storage I am getting the following exception

com.google.firebase.storage.StorageException: An unknown error occurred, please check the HTTP result code and inner exception for server response.

Here are my Gradle dependencies:

apply plugin: 'com.android.application'

In the manifest file:

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-feature android:name="android.hardware.camera" android:required="true" 

I have also written code for runtime permissions.

In onButtonClickListner() method: { if(permissionsGranted) dispatchTakePictureIntent(); }

The code for capturing picture is here:

       private void dispatchTakePictureIntent() {
            Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            try {
                File dir= Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
                File imgFile=new File(dir,GetPictureName());
                image_uri=Uri.fromFile(imgFile);
                startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
    
            } catch (ActivityNotFoundException e) {
              
            }
        }
        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
                Bundle extras = data.getExtras();
    
                Bitmap imageBitmap = (Bitmap) extras.get("data");
                data.putExtra(MediaStore.EXTRA_OUTPUT,image_uri);
    
                imgUpload.setImageBitmap(imageBitmap); // imgUpload is an ImageView
saveToFirebase();
    
            }
        }

    private void saveToFirebase() {
        FirebaseDatabase database = FirebaseDatabase.getInstance();
        FirebaseStorage storage = FirebaseStorage.getInstance();
        StorageReference storageRef = storage.getReferenceFromUrl("gs://smart-worker-c73c4.appspot.com/gs:");

// Create a reference to "file"
      DatabaseReference myRef = database.getReference("posts");
        String id=myRef.push().getKey();


          storageRef.child("images").putFile(image_uri)
                    .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            // Get a URL to the uploaded content
                            Uri uri = taskSnapshot.getUploadSessionUri();

                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception exception) {

                        }
                    });

        }

And here is a screenshot of my Storage Bucket:

A lot of thanks in advance for your time and consideration.
