'We have detected an error in your custom storage adapter.'

[Albert-Henk]

I can't seem to my storage adapter working. Whenever I run 'ghost start' I get an error message saying there's an error in my custom storage adapter.

This is my config:
(I have already tried several things like adding or removing signatureVersion and pathPrefix)

Does anyone know what the problem could be? (I'm using a Digital Ocean droplet for my ghost instance.)

I also already tried to run 'npm install' agian, like @yuhr123 mentioned in another topic, but that didn't work for me.
