GCLOUD results are not being stored on the result bucket

This could be a configuration error or misunderstanding on my side, but I cannot seem to find where the issue lies.

Running Imagor version 1.4.14 on Kubernetes.

I'm expecting the raw image to be loaded from the loader bucket, and processed images to be stored on the result bucket in the images/result folder, but I don't see this happening. Also I'm not seeing any errors or logs indicating that this is being attempted.

These are the settings I'm using. Am I missing something?
