Ghost 3.28 - Crashes when images larger than client_body_max_size limit uploaded

Hello!

I am using Bitnami Ghost 3.28.0-0 on Amazon Lighsail instance with the following specs: 512 MB RAM, 1 vCPU, 20 GB SSD. I am also using the Cloudinary storage adapter.

Every time a user attempts to upload an image > than the client_body_max_size (as described in here https://ghost.org/faq/image-upload-issues/), the server crashes, and returns 502 errors. There is a brief flash indicating that the image is too large before this happens. Any thoughts on how I can resolve this?
